The OOB mechanism that I referred is about pre-populating a database in the
Registrar. It is not a "signaling protocol" that does anything similar to
SIP. We still need log on/off behavior and the intent is to use REGISTER for
that.

What is non-standard about using REGISTER the way I've described it? I don't
think I'm bending the semantics of it. Is it carrying a domain name in the
Contact URI that is of concern?

Even though we've a "closed" system, we don't want to do non-standard
things. My Registrar/Proxy is the one that dereferences the Contact URI that
came in the REGISTER. What's wrong in saying that, well I'm going to dip
into my database to resolve that domain instead of issuing a DNS query.
