I've pretty much shared your opinion about honey pots, but one idea I've
been toying with recently is deploying "canary" systems internally so that
if someone smarter than me does get through the perimeter, if they hit the
canary system it'll alert me. I'd probably use just a default redhat 6.0
install (got enough root holes there to make it east), call it something
tempting like "cybercash" and then modify sh/bash and csh/tcsh to e-mail a
warning anytime they are run (and turn off cron jobs to eliminate the
false positives).
