You're right in my case I'll have to use server based.
I've performed some load tests with SER and noticed that PUBLISH & SUBSCRIBE
requests uses lot of CPU power while NOTIFY request are not that cpu
intensive.
Additionally, you also have to consider SIP implementations.
There are not thousands of SIP clients which supports all
presence modes. Some clients supports end2end, some clients
support server based. The same with SIP proxies.
Conlusion. Get some clients and implement both scenarios and
find the one which fits your needs.
I'll be using a GnomeMeeting mod client and server based presence should be
enabled.
Thank you for you information,
Vincent
