In any case, if Pekka is correct, that's *exactly* why this
draft and RFC 4594 are needed - to lay a minimum foundation on which
ISPs can build operational practices and SLAs.

It's always been clear to me that voice and video would be the main
drivers for uptake of diffserv, and Marshall's comments confirm
that. As that type of traffic grows, ISPs won't have any choice.
Guidnace from the IETF seems entirely appropriate.
