Just a random bit of trivia from me here:

Qemu can (I think) export a Linux directory tree to a guest as a block device 
formatted with a FAT filesystem (!).  The host Linux can't modify the files 
as far as I know (I'd suggest that'd be impossible to do safely) but there 
was talk of adding write support for the guest...

Anyhow, it could be handy for sharing a static filesytem tree or having guest 
FAT filesystems be easily accessible.  In theory this should be doable in Xen 
since the Qemu device models are used but I don't know if it's plumbed in...

Cheers,
Mark
