pts has interactive and source modes which would permit the pts process
to cache the up/down information between requests.

There is no reason the vos command could not have equivalent
functionality which would significantly improve performance in a number
of ways.  Besides remembering which servers are up/down the same rx
connections can be reused and repetitive rx security class
challenge/responses can be avoided.

I would prefer to see someone work on this approach combined with
jhutz's VIOCCKSERV suggestion if a cache manager is installed on the
local machine.
