There's a bunch of program that doesn't need much more than read/write to a specific limited part of xenstore.
- Guest agents (reporting stats usually)
- things listening to some actions (snapshot yourself, export some storage thing, etc..)
Perhaps a variant of the restrict packet would be enough to drop some privileges
of the xenbus connection (at connection time) to read/write to a specific path.
