According to the end to end argument, that's simply impossible,
because intermediate equipments holding packets not confirmed
by the next hop may corrupt the packets or suddenly

has to never? Even though it must, when it goes down.
Lose a bit, lose everything.
You totally deny FEC. Wow!!!
And ROHC is an IETF product.
I'm pretty sure the saving on headers is
Martin,
An article like this is the best reason why we should never finally resolve the
buffer bloat issue: Doing that would take away the opportunity for
generations of researcher to over and over regurgitate the same proposed
improvements and gain PhDs in the process.

I've no idea about the example quoted, but I can see some of their motivation.
TCP's assumptions (really simplified) that loss of packet = congestion =
backoff
aren't necessarily so in a wireless network, where packets can be lost without
