I read through the entire thread and the concept of a plastic bowl is really scary to me. I think at this stage it is an accident waiting to happen but of course I have not seen the actual product. There are a number of comments about filtering cold oil - according to what I have seen with my filtering setup (flow powered centrifuge) this will not happen. Before somebody says 'yeah but it's a completely different concept' ... that is true but the centrifugal separation action is similar.
A few answers to your questions:
Throughput on a centrifuge type cleaner is related to viscosity of the product to be filtered, the difference in mass between the 'clean stuff' and 'dirt' among other things. As such, if you heat the oil you will increase throughput and if you want to only filter out large chunks you can increase your throughput. A figure of 1 gph is meaningless without specifying viscosity and filtering level.
When filtering WMO, keep in mind that you will not filter out carbon. The oil will look just as black coming out as going in but you will have removed larger particles.
BTW, although a centrifuge will get out water that is separated in the oil, it will not (IMHO) get out water that is somehow bound to the oil.

The rotor is nylon - easily capable of withstanding up to 150F and higher, although I tested the device for 10 days straight at ambient air temps (90F - what I would call cold filtering - no heat added) and I obtained the results I mentioned: 0% water present, none, nada, zilch, verified by Blackstone Labs. That was from a 1.8% water saturated oil source. Your results with your centrifuge may vary, but this is what I obtained with my centrifuge - it works and is so simple to use. We ran it at 1 gph, but faster processing is certainly possible, we just decided to test for 1 gph. Of course as you said adding heat may aid in more efficient higher speed processing. We figured 1 gph would be sufficient for the typical user; I can process a month's worth of fuel for my VW over a weekend - that is with minimal attention - just set it and forget it. However, Budd's design (which my CF is based on) should effectively process WVO at 2 gph (according to Budd's extensive experience) and I wouldn't hesitate to do so unless the oil was known to be of poor quality, in which case I might try .5 gph or something else - it depends on the oil. I suggest you get to know your oil source and use Blackstone Labs to verify your efforts.

Looks interesting and very cost-effective, but still appears to be in "design" phase, and has the hallmarks of an "eternal engineering" project. I'm sure it works, but it's a long road between prototype and saleable product (I know this all too well - I'm not trying to burst the balloon, but I've got some experience being on the engineering side of such projects.)  I'm probably going to put myself in line for one, but I'll not hold my breath for delivery in a timely fashion. :-) I was really interested in the simplecentrifuge.com unit, but I just can't pay that much right now.
Apologies if some of these questions were answered in the other forum, but the sheer volume of posts is a bit overwhelming:
 - how many watts does it draw during operation?
 - what are you planning to ship? turn-key, or just the rotor, or parts kit or...?
 - is 1gph the best it can do?Â
 - can you get better than 10 microns with <1gph flow?
 - have you tried it with WMO? (not that it should make a big difference...)
My Lister (16/2) will consume about .38 US gallons per hour at ~75% load.. This means that there is slightly more than a 1:3 ratio of runtime for this system for the hours that I'm running my engine. This seems a bit slow to me (1 gph, that is) but for the price I'll just get two since I can therefore have a "spare" in case one melts down. I'd probably be processing around 100 gallons at a time, since it makes more sense to buy/obtain used oils in larger quantities.

I don't know the total electrical draw off hand, but it is a 110VAC motor and runs on a 15AMP circuit without tripping the breaker.
The system will be sold as a turnkey unit, complete with a rotor removal tool.
The CF can filter down to 1/10 micron, but remember "filtering" is relative. In general, a filter meets a specific rating if it traps a certain percentage of particles matching that rating, ie., 97% of 1 micron particles trapped may qualify the filter for a 1 micron rating. In order to determine the percentage trapped, the amount of particulate present in the original sample must be known. Blackstone Labs was unable to determine my source oil sample's original particulate count because it was "too dirty". However, I ran the same sample through a 10 micron rated whole house water filter under the same conditions and the CF removed over 50% more particulate.
I haven't tried WMO yet, but I plan to. I expect to be using a dozen or so eventually to process both WVO and WMO.
The CF is through with the design phase, excepting the lid/integrated brake, which actually has been designed also, just not yet implemented. It will be on this next and last prototype, essentially the production prototype.
