Yeah, I think we're using that somewhere too.

Pot-ay-to, Pot-ah-to.  Any sufficiently insane kludge is indistinguishable
from a Unix feature (or did I get that backwards?)

That said, I'm tempted by Wes's up-imapproxy idea for our WAP server.
It's written in PHP so we don't run it on a box inside our trusted
network, it just talks IMAP with the plebs.  It currently uses
imap_pconnect which has the lovely /feature/ of returning "too many
login failures" rather than the actual error message if you enter the
wrong password.  Using a proxy to avoid continual reconnects but that
could actually return a sane error message would be very nice.
