I feel that it is impossible to setup some some
systematic approach to
costs when one sort of direct link is considered a general problem.
I don't understand what that means. Aren't all direct links the same, at least
as far as DECnet cost is concerned?
Unless you're saying that you consider the bridge to be a "direct link"
despite its extra hop thru psilo. If we go that way then any and all links are equivalent
and you've rendered my only goal superfluous.
