After quite a while, a few betas, a lot of time on valgrind, and a ton of computers wrapped around me, I've got a 1.0 release out for all my major tools.
http://cryptohaze.com/multiforcer.php has the multiforcer downloads.
http://cryptohaze.com/gpurainbowcracker.php has the GPU rainbow table tool downloads.
There's also a wiki up now - http://cryptohaze.com/wiki/index.php/Main_Page
So, go at it! Bug reports are welcome, though I'm aware the networking support with the multiforcer is a bit glitchy (and will likely be fixed in a release in a few weeks).
