we've already discussed this on #irc, but for the list archives (in case 
someone websearches for this), the NUTAG_IDENTITY() is still work in 
progress, and is not currently used by the stack (I now added a note to 
documentation).

But I think we have two different use cases here: passing alternative 
identities over a single SIP account (one "From:" identity, but a 
separate tag in the Contact header), and handling multiple 
separate registrations with one nua handle (= basicly one set of local 
UDP/TCP ports).

NUTAG_IDENTITY is needed for the latter, although a workaround is to 
maintain the identities yourself (as done in tapioca-sip).

But for the former one, I guess you only need to add some custom tags to 
the Contact header for each registration (multiple username parts maybe). 
Brian, does this match your requirements? For this, something simpler than 
NUTAG_IDENTITY() would be enough (or maybe already possible without 
resorting to the 'nta' interface).

Although, to handle incoming registration, you need to start using the 
'nta' interface anyways, as 'nua' has no support for this...
