I'd be interested in discussing test automation pieces in San Diego
also.  I have my own tools as well (doesn't everyone?), and I
have the same attitude as Jason.  I had thought about submitting
some for /tools/testing, but I don't want to clutter
that up with similar or duplicate tools.  If there is interest in
unification, I'd be very happy to participate.
