This is mostly about how they got IMAP to the treos, but at least they are using the treos.

It's not often that the songs of '80s hair metal bands intersect with IT management, but our recent foray into setting up an open source IMAP server at InfoWorld to deliver mail to the executive team's Treos (see “Mobile Messaging With Open Source”) had me singing a couple of lines from an early '80s Motley Crue hit "She'll use her time up / Have nothing to show" (read on for the name of the song).
Another mention in his blog about traveling with the treo. also mentions Bob's Alarm and basejet.
