Very simple... it will not run on my system (or my gf's). Been there, checked into it, it's impossible.
I find this an interesting venture and I applaud all those doing so that can. One should be careful not to assume those that don't have less than a good reason.
Another reason others may have is an edge of paranoia about running someone else's programs on your own system. In the age of Bush's free reign Orwellian spy machine, that would not be inconceivable.
Since I can't run it, I didn't probe further but I am curious... is there any sense that this data is double checked? This is the age of hackers who like nothing more than to screw things up. What is to prevent a hacker from screwing with science by creating plausible but wholly false results (during or after processing)?
