IP header compression only works well over a link where you have few
flows (fewer than the number of slots for compression) so my customers
get to save some bandwidth on their access links and I get the
privilege of wasting a lot in the core.

But I certainly take Iljitsch's point: maybe I'm complaining about VoIP,
not about IPv6.
