TCONS is absolutely not suited to the spacelink.  Its intended for
onboard only.  Of course theres no reason why someone couldn't try to
use it for a spacelink- or for a proximity link for instance, but the
protocols aren't set up for the kinds of issues applications like that
present.

I think Rick is calling it a service for the purposes of TCONS- its a
service for the TCONS network layer.  Its true that its not a service
for userspace.
