Birds of a Feather: but what Feather?

As most of you know by now, the December Tri-JUG meeting is a little 
different; instead of
one formal presentation with a designated speaker, we're having "birds 
of a feather" sessions.  So
people will a common interest gather at a table to talk about $FOO and 
eat pizza.

What I wanted to do was ask: what are some topics people are interested 
in for the BOF
sessions?  I thought it might be good to have some ideas floating around 
in advance
of the meeting, instead of leaving it completely to "we'll see what 
groups happen to form."

So, to throw two ideas out there: if anybody is interested in discussing 
social networking
or the semantic web, I'd be interested in participating in either of 
those discussions.

Anybody else for either of those topics, or some other topic?


TTYL,

Phil
