This is completely off the top of my head, but since we're talking about perlmonks shells, how about:

www.perlbeach.com
www.monkbeach.com

yes? no? probably not, but it seems that logging in to perlmonks is a tiny vacation in the workday...

Other suggestions?

Update:Sorry, sorry, that should be:

www.perlbeach.org
www.monkbeach.org

humblest apologies... :-)
