kobi,

this does not sound very promising. i would have thought that adding
support for such a simple event package would not be more than a couple
of hundred lines of code.  openser von slides say about presence
implementation:

modular design for presence
one presence engine
several (specialized or not) components to inject presence
information
this design enables:
presence support for non-SIP entities
publish the CPU usage of your desktop
publish weather information
publish the stock size from your store
presence support for old SIP phones
easy creation for custom/complex presence extensions

there are several sip phones that somehow can do that (nokia phones for
example).
