Most carrier ISDN switches can do X.25 service on the D channel without explicit X.75. X.75 becomes necessary only when you go from one telco to another, and is probably best avoided. ;-) Since AO/DI would primarily be interesting to access *local* ISPs, I don't think this is an issue. 'Difficult points to AO/DI' seem to lie mostly in the carrier's facilities and organization, not in the IP gear. For a MAX or Pipeline it should just be MP across nxB + an X.25 VC; I don't see how that can be so terribly complicated...?

Somehow I don't think our 100 > million-odd modems will go away that fast. I was only quoting established networking gurus. I may have had it backwards, though. As Jamie Penner (Canada) noted on this list, they (and us, over in Europe) may have to deal with monopolies that push ADSL on the basis of cross-subsidies from their telephony services, long before it happens in the US.
