Understandable.

I will endeavor to find some free time over the weekend to have a
play with the xenstored code, and see if I can watch events from it.
No promises at all, but if I get anywhere I'll post an update.
Right now I can use "xenstore-ls" to get a snapshot, and I guess
I could do that every five seconds or so to be able to detect newly
created domains, and existing ones which have been shutdown.
That's not ideal, but for a first pass should let me get something working.
Downside is I'd probably have to write the daemon in python to
get it into the core, right?
