Let me go on the record that I think this would be a spiffy idea for an official feature, and it should require next to no effort at all. Just have a text-area be defineable in Emplode, that (if defined) will get displayed for 5 seconds at startup, so you could have something like:

      Empeg Car Stereo
Property Of:  Derek Balling
If Found, Call xxx-xxx-xxxx

Excellent anti-theft potential.
