With version negotiation, the foot is in the door.  Given agreement on a 
particular versin number, it is now possible to look at further ddata in 
the hello packet and negotiate anything that version wishes to.

But unless there are multiple implementatinos of the netsync protocol, 
or unless system adminitrators choose to make some features unavailable 
for reasons of their own, I don't see much point in real capability 
negotiation.
