And I'm not sure I understand that sentence. :-)
All links are the same, I guess. They all have a cost associated. The 
cost might be different. Which would suggest they are not the same. So 
what do you mean?

Yes, I consider the bridge to be a direct link as well. All our traffic 
is carried over IP, meaning it is running through a number of hops in 
between that are invisible. The host running the bridge is not, in my 
view, any different than any router, or the extra layers that a Multinet 
link is running through inside the VMS box, in order to carry over the 
DECnet traffic into an encapsulated UDP or TCP stream.

If the encapsulation happens inside the machine, or externally, how much 
do that matter? Especially when the external encapsulation might in fact 
be way faster?
