<p>Hello,</p>
<p>sip presence spec doesn't have many client library implementing
it, so if you don't want to invest in that direction, it is minus,
I expect xmpp has more options here.</p>
<p>In terms of scalability, I cannot comment on xmpp, as I never did
any large installation.</p>
<p>SIP has a plus in routing flexibility, given by the headers and
the fact that you can decide easier what would be the next hop in
the path. Another plus with SIP would be integration with 4G
networks where the core is using SIP for routing.<br>
</p>
One issue when running two protocols is the operations, practically
there are two different infrastructures, one for sip and one for
xmpp, adding the overhead of maintaining/monitoring/upgrading over
the time.<br>
<br>
If you want the basic presence features, it should not be that
complex even with sip. If you want to fully implement SIMPLE specs,
then might be a lot of work.<br>
<br>
As a conclusion, if there is going to be use only one type of SIP
client with IM&Prensece that you develop, then probably is ok to
go for this way. If you expect to have many types of SIP IM&P
clients implemented by different vendors, I expect difficult times
ahead to get them work together nicely.<br>
<br>
