No, there's no generic mechanism for sharing char devices. The way in
which it makes sense to multiplex devices between domains is typically
very device-secific:

With a dvice like a tape you'd presumably only want to let one domain
access it at a time, perhaps with a hard interlock as to which tape is
in the drive. Fortunately, the bandwidth is pretty low, so it's probably
easiest to setup a network based soloution rather than doing something
Xen specific. I presume such daemons already exist (?)
