Can it please be explained how the IMEI URN when used as stated in http://datatracker.ietf.org/doc/draft-allen-dispatch-imei-urn-as-instanceid/
Is any more harmful than as the IMEI is used today by over 90% of mobile phones in use today worldwide?
It survives device wipes, which usually happen upon change of device ownership.
I’m not an expert in your application domain, so pardon me if this question is hopelessly naive: It seems that this identifier is related in some way to SIP sessions. It seems that it would be a common operation to launch a SIP session on a device such as a WiFi-only tablet, or an iPod touch, that doesn’t have an IMEI. Is this a problem?

You're not demonstrating that an IMEI is just as good, you're
demonstrating that a UUID is just as bad.
