agentz,

The TagSet stuff in TD is cool, btw.

I want to, but I don't know when I would be able to commit. Maybe sometime
over the next month, but probably not in the next week or two.

Yeah, I wasn't precisely pleased with this myself, but it would have been
flexible enough for what I was considering at the time. :-P
