Ok. Perhaps I can help with making fixes where they are appropriate.

I guess a realm=zxxxx entry might be sufficient as the SIP client when authenticating will have an address of the form To: sip:[EMAIL PROTECTED] rather than @IP of the client.

I hadn't understood the source too well in that respect as there was also the :port bit mentioned. if this format register => [EMAIL PROTECTED]:[EMAIL PROTECTED]:port/localpart is acceptable I can look at modifying the existing source to accept this format and using it appropriately. That shouldn't be too hard (I think). Thanks for the feedback.
