Generating models or morphs on demand could be really quite tricky. What could be easier is showing the current measurements, possibly with highlighting of unlikely combinations. Would that be of use?

Also consider the motherboard chipset. I've had a lot of problems with VIA chipsets before, especially when under load. KT266A and KT333 seem to have been a lot better though...

I think the point that this isn't a movie is the important one. I code for a living, and it isn't writing the program that's the time consuming part, its the debugging. Which means if you're lucky, and it works almost first time, you can make incredible progress, while at times its possible to hit problems that take anything ip to weeks to solve. There's a saying that if builders made buildings the way programmers write programs, the first woodpecker that came along would destroy civilisation. The counter-point to this is that if programmers wrote programs the way builders make buildings, all code would be a variant on "Hello World"!

I've got to say, I'm not poor, but I only do graphics as a hobby, and while Poser isn't quite as expensive as I might be willing to pay, its close to the ceiling, and even just paying for the upgrade is going to leave a noticable hole in my finances. I think Curious Labs have the right idea - price (relatively) low, hope to make more sales through doing so.
