That's the fundamental disconnect we've been trying to communicate: TCP
*won't break*.  None of the rules of TCP are broken, from the wire's
point of view.  The OS merely gets a richer API, from the application's
point of view, to optimize the TCP protocol implementation to serve a
wider variety of needs.

That would be good to give the customer a choice of access devices with
which to get on the network, and let the market device what is best,
instead of AT&T dictating what's allowed.  I'm getting deja vu of a
famous legal case from 27 years ago.

Wow, that's news to me, that it allows this.

Have the limitations in these documents been addressed?  If so, kudos to
AT&T.
