Hello,
In the past week I was fixing the receive buddy's presence mechanism. In the first weeks I've implemented only the Telepathy part of this and back then I didn't know that I should get this information as a SIP NOTIFY message.
Now the SUBSCRIBE and NOTIFY mechanism is working at resiprocate and you can see some images at my blog [1] and look at my commit [2]. For now the commit is full of debugs and I will clean that when I got everything from this commit working (I'm still working on the send presence functionality).
This current week I'm planning get the send presence working and continue to work on send/receive text messages.
