[reSIProcate] extended presence

[Ron Shacham]

Hello.
I have been developing a SIMPLE interface for a location tracking
technology, using resip.  I have updated the Pidf class to support
location extensions in pidf-lo, currently in the geopriv WG.  I would like to
extend the presence support in resip by including this, as well as
possibly RPID extensions.  Would there be interest in such a
contribution?

Regards,
Ron
