This is an interesting assertion. The MID is an AAL3/4 level identifier,
and as such _is_ 'end to end' (where we are talking about the
ends of a cell flow terminated by AALs). This quite definately gives
them a broader reach than individual VPI/VCI values (which may change
along the path of a VCC), or just VPI values (which may change along
the path of a VPC).
