Well, if "fs getserverpref -vlservers" could be told to only return 
answers for a given cell, the client userspace commands could use that 
(of course, via API call) as a way to query the (longer-term) knowledge 
of the client. If the AFS client is not running on that host, they'd 
just fall back to using CellServDB directly, as now.
I don't think something similar exists for the PTS database, though.
