Dave,

 I agree X.75 cgoes contrary to internet philosophy. My
suggestion is that something between the current route binding
in X.25/X.75, and the fully dynamic routing of IP is required
plus some.

I think You need some kind of weak resource reservation scheme,
combined with some means for end to end protocols to find out what the
resources out there are, since pure feedback from the end to
end protocol will give you information too late to adjust mtu's,
rtx times etc, and will always give you unstable algorithms.
