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

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

Feedback is, as usual, welcomed.
