What do you think about storing this data in an SQL database? For example,
I'd like to be able to find out which machines have version X of package.
It seems SQL queries would cut down on scanning lots of state files to
handle situations like that.

I like this idea better; being able to force immediate updates or package
installs from the management host would be great.

I'd also like to see a way for clients to auto-register themselves. We turn
machines over pretty frequently, using autoinstall to build fresh machines,
so having to manually enter them would be a drag. The management host could
run a daemon that clients could connect to and register themselves by
specifying a shared secret or somesuch.
