Fair enough.

I don't think basic SIMPLE presence deserves that much care. A "high-quality"
SIP deployment should use XCAP for server-side contact list management. Plain
SIMPLE with peer-to-peer SUBSCRIBE requests is not too sane for network usage.
In fact, I don't know of any significant user base using anything SIMPLE. Does
Ekiga do it without XCAP?
