As I mentioned in my other e-mail, it would be possible to implement a fairly 
close approximation to hostfs under Xen.

I'm actually working on a Xen shared filesystem (although I'm currently 
distracted with other work).  This is intended as a replacement for NFS but 
implemented in a way which is highly optimised for a intra-machine sharing 
under Xen.  This will make a substantially more complex implementation but 
should give way better performance and resource usage.

A prototype implementation will be announced on the list when it's ready :-)

Cheers,
Mark
