I like the built-in socks part.  Cute.

Perhaps the next version of socks should provide some sort of
encrypted token exchange to allow only 'approved' clients to connect, even
from inside your bastion host...

Um, I thought the sendmail hole the the Morris worm used was
the infamous 'wizard' mode, where you telnetted into the sendmail port
and typed 'wizard'.  Then sendmail just asked for a password
and if you provided it, dropped you in to a root shell.
