My attention is a fickle thing... :-) But if I ignore you for too long,
naturally it is best to ping me via IM since after all I *do* work on an
IM technology!

Yes, we have more of those on the way -- I am planning on also writing
up formats for video/movies (what you're watching), gaming (what you're
playing), groupchat (what rooms/channels you're in), and perhaps a few
others.

Sure. IMHO the existing clients will become more sophisticated once we
start rolling out JEP-0163 implementations (soon!), but a nice proof of
concept can't hurt.

Nope, that works.

One thing that various Jabberites have talked about here and there is
the concept of an XMPP daemon that runs on your machine and enables
various applications to tap into the goodness of Jabber. So your iTunes
or Songbird instance could push out tune info, your calendaring app
could push out activity info that it knows about, and so on. Each one of
those apps would have a "pipe" to the Jabber world via the daemon. But
no one has ever gotten really far with that idea.

Another approach is to write a plugin for an existing client. Exodus has
a nice plugin architecture, and one of the Psi developers is working on
a plugin system as a Summer of Code project.

Or naturally you could roll your own using one of the existing Python,
Ruby, Perl, Java, C, C++, or C# libraries.
