Presence and IntComm WG

[(Dennis Baron)]

> The documents seem more SIP/SIMPLE-centric to me.

Thanks for the feedback - it shouldn't sound that way - but maybe some
of the WG's past is coming through :-) .

I agree that the federation is there - but I think we need decide if
we want to promote a common addressing scheme - ala. SIP.edu.  It
seems like we should to me - but of course I'm biased - I'd be
interested if others think there are reasons not to.

For rich presence I think the WG needs to think more about _what_
would be of value - eg. use cases, demo's, etc. - as you point out the
standards are mostly there.

> I find the focus on commercial vendors puzzling.

Well, in part this is keeping the Internet2 corporate members engaged.
But I think the larger goal is to have systems that interoperate and
provide expanded functionality across platforms - both server and
client.  I think we should offer an open-source "package" or cookbook
that campuses can deploy.  How much the group can build will depend on
the resources that we can muster.  And for some campuses there are
advantages to being able to just "buy" a commercial package.  Ideally
they should be able to take this route without loosing any
interoperability with other campuses.  Similarly, users should be able
to choose open-source or commercial clients without loss.

I think you're other comments were in response to the older "Features
List" - which I think was done before we decided to re-focus on
promoting XMPP-based deployment.
