Subject: Re: Do the precompiled binaries for windows support

It's just helpful - since this is mostly a hobby (meaning my work 
doesn't fund hardware, I have to use my own) I don't spend enough time 
cracking passwords to warrant a separate machine with teslas and fermis 
to run linux on. It saves me the trouble of continually having to reboot 
a machine for just one purpose.

That being said, I'm happily using JtR on both mac osx and linux using 
MPI - I'd just love to be able to remotely hit a command prompt on my 
windows machine to leverage that card.
I suspect that if a build did surface that supported cuda on windows a 
huge tide of new users would appear in the community.
