We always suggest a fault-tolerant network (fully interconnected is 
preferred, of course).  So it's still on an SFS reliability issue.  I'd 
rather focus some attention on LAN (IP)-based ISFC configurations in order 
to eliminte intermediate nodes as a point of failure.

I appreciate the auto-release issue, but I don't see us changing that 
behavior.  It would be a Big Deal to redesign the SFS client.  For myself, 
I'd probably write a nucleus extension that periodically tries to 
re-access my preferred filemodes if they aren't accessed.
