The field you want, in general, is called accessibility. I tell you that so it can help your Google and other searches. I encourage you to reach out to the organizations listed on this Wikipedia page. I know some of them personally as I'm blind and a PhD student in computer science and an accessibility researcher, so I'll be more than happy to perform introductions on LinkedIn, email, twitter, whatever you like, just let me know. Here's the Wikipedia page listing some organizations. I'd start with Able Gamers. Mark's a good guy. http://en.wikipedia.org/wiki/Game_accessibility Next, I'd encourage you to get on twitter, if that's possible. I can connect you to tons of folks to cover everything from one handed typing approaches (both paid and open source solutions), speech input alternatives, strategies developed by other users of technology with the use of only one hand, and so forth. I'm @SinaBahram on there. Just drop me a line. Btw, the accessibility community often goes by the numerical acronym A11Y, so look for #A11Y or just a11y when Googling around, and that can help some of your searches as well. Sorry if this post is a bit disjoint. I would love to leave more comments on Slashdot and interact with it more, but Slashdot has repeatedly ignored my various emails and other attempts to reach out to them, since I use a screen reader and there are some serious accessibility issues that could so easily be fixed if I could just get ahold of the right person *poke poke to anyone who reads this*. To you or anybody else looking for more information on accessibility, technology used by folks with disabilities, etc., just contact me via whatever mechanism you like. It's all on my site, which I'm not sure my profile links to, so here it is. www.SinaBahram.com I hope this helps, and please don't' hesitate to contact me so we can get you connected to the right folks to get you gaming again.

This reminded me of previous work carried out by researchers at NC State. Here's a YouTube Video

Unfortunately such a cluster doesn't exactly optimize sheer performance because there's lots of communications back and forth, no shared data model, etc. Granted, due to the low memory constraints, the data could be replicated on each Beowulf compute node; however, then different costs are assessed for intrathread communications. Furthermore, I'm guessing you just mean put a few processors in each box and get 10 or so of them, but at that point is a Tesla solution not better?

Is this question worth reposting so that it filters up the list for tomorrow? I don't want to break any written/unwritten rules with respect to being annoying/irritating/pesky.

This is a good point. Thank you. Again though, at these prices, it's almost worth rechecking calculations than paying for such an insane markup, no? I look at the various GTX cards, then at the Tesla, and I come away unimpressed at the differences per unit cost. So, no, I'm not sure that I don't need ECC. I'm willing to entertain the various possibilities though.
