It is still a work in progress.  I've been making some progress with 
Eyebeam, to the point where PA is sending NOTIFY to eyebeam.

I'm a bit puzzled how the error message ended up before content-length 
in the response message.  Please send patches to the list and CC me and 
I'll apply them.  If you have not fixed the problem with ser not parsing 
the headers of this subscribe message, please send me a copy of the 
message and I'll see if I can fix it.

Thanks,
