The back port is not yet complete, so Divmod Sine is still more functional
and easier to use (as well as less buggy) than the SIP code in Twisted.  I
would suggest either helping to complete the port, or using Divmod Sine

You can read more about the progress of the port in the issue tracker:


(including a detailed list of what remains to be done).

Probably, but I don't know of any examples of doing so.  The Divmod Sine
code definitely provides this functionality, and you can find a registrar
implemented in Divmod Sine itself.
