I don't think this statement on your website makes much sense:
A user can download Wisecracker=E2=84=A2 on a GPU cluster virtual machi=
ne
provided by Amazon EC2=C2=AE and reverse an MD5 cryptographic hash for
a 6 character password in about 20 minutes if using 1 virtual
machine or in about 3 minutes if using 2 or more.
What does "2 or more" mean here? If I use two machines in parallel, that's
more than six times as fast as only using one machine? Seems weird to me.
