Excellent!  Then I have no worries at all about it.

You mentioned the current design looks a lot like a file system, any
thoughts on actually using the file system?  Either within the normal
file system (within something like /var/xen/<domid>) or as a pid-like
/proc entry (like /proc/xen/<domid>).
