yes- i agree this is all too vague.

a. you have wires carrying multiple (link+net) protocols
b. you have routes these protocols allow
c. you have multiple routing info exchange protocols which also run over 
these
wires

a+b+c =>
1. you can reduce to one routing info exchange protocol,
2. you can reduce further to one set of routes common to all (link+net)
protocols
(3. you could run the same routing exchange protocols but with different
addr spaces run different route calculation/algorithms - though that
sounds like asking for trouble)

1. may be desirable to reduce the number of copmplex things like
routing algorithms etc to worry about
2. may not be desirable, since different (link+net) protocols
may have different effects and so on on nets

by the way, my belief is
we will want explicitly 1 and not 2 for the future uk-US
connections.

have i got this right?
