Perhaps I'm asking the wrong question.  I'm looking to allow only one registration per user in the sense that if a second successful registration comes in it will replace tne existing one.  My approach so far is to use a max_contacts=2 and the lookup() function with the "b" flag to retrieve only one.  max_contacts=1 returns a 503 to the new "replacement" registration request, so that's out.

Perhaps the hot ticket is to run an all-DB mode running a manual mysql query with avp_db_query after successful REGISTER authentication but before the save() so we can remove any existing registrations before the new one is saved.  Thoughts?
