iirc, we discussed this before. This a new feature that is not common at 
all in clients and thus hard to implemented -- you mentioned that some 
Nokia phone supports it, if I am not wrong, but I have no access to such 
device. In addition, afaik, out there were some complaints about 
security in this approach.

What I try to solve now is eventual bugs in existing implementation. 
Kamailio version of SIMPLE presence is running just fine, I have most of 
the modules running in production. I feel some trends in suggesting is 
not longer developed, which is completely false. There was one open 
issue, related to a potential race reported by Alex Hermann, which is in 
my to-do list. Then Klaus reported something regarding the contact, 
which is going to be fixed as well, probably would have been done by now 
but Klaus said on devel list he has some patches to commit.

As a matter of fact, I think Kamailio has the most complete SIMPLE 
Presence specs implementation out there at this moment, being the only 
one with an integrated xcap server. That was added with the latest 
release, so it is simply wrong suggesting presence extensions 
development is stalled.

On another hand, following all new crazy extensions from SIMPLE IETF is 
not a big priority, since no phone vendor is actually looking to add 
them. But the core presence services and rls are here and going to be 
developed. We have to admit that the latest SIMPLE spec were not really 
much in touch with reality, even IETF guys realized that, hopefully we 
will see alternatives as another group at IETF is looking to reuse XMPP 
for presence in SIP and others try to find easier presence architecture 
for SIP.

Cheers,
Daniel
