I look forward to having the time to try it out! :)

Hmm; well, I'll have a better opinion after I've played with it, but
that seems to brittle to me. In particular, the conversations seems too
one-sided. It seems like there should be some way for the client to say,
"Hey, some of this stuff conflicts with other things I've got, what do I
do?" and for the right negotiation to happen. I run into trouble like
this all the time with, e.g., apt-get.
Thanks for being so enthusiastic!
