It seems you want to parallelize your computation on a single  
computer, so what benefit do you find using snow/snowfall over using  
the foreach w/ multicore backend?

Just curious because I've moved off of any snow* related packages  
since I only parallelize on the same box and find that the foreach/ 
doMC combo works just fine.
