This boils down to whether an event-driven approach can be used instead of the
current polling-based one (running the script via cron).

When using an intermediary "mail processor", POP3 is not an option: there's
still an app *polling* the POP3 mailbox and then firing up the script. 

So there only one alternative: using IMAP with IDLE support (push mail). Yes,
the Sun Java System Messaging Server supports this. A python/whatever script
might be continuously connected to the mail server and, upon receiving
notification of a new mail, fire up the script. However, this breaks the KISS
principle since:
* it involves yet-another script (daemon-like)
* it relies on the delivery of the mail from Launchpad and on the reliability
  of the chosen mail server
* a bzr up (followed by a bzr revno) is not that expensive, given the current
  machines.

But, if the powers that be decide it's worth, I'm willing implement this
alternative solution.

Feedback is, as usual, welcomed.

Cheers,
Mircea
