it looks like, among other things, the provisions for shared memory
have been redone ("grant tables") such that domains can grant other
domains access to specific pages (rather than the entire memory), thus
allowing unprivileged domains to run virtual device backends, or other
forms of direct communication between mutually untrusted domU's.

And, as I've mentioned before, XenStore/XenBus, which replaces (AIUI)
the domain control interface.
