Who cares?

Ditto.

Vern please read the document: "This draft specifies an IPCP (PPP
Internet Protocol Control Protocol) option that allows SIP clients to
locate a list of SIP proxy servers that is to be used for all SIP
requests. This approach is applicable to a system utilizing PPP for its
link layer protocol and IP address allocation (ex. 3GPP2 Packet Data
System)."
                                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Presumably, 3GPP2 will be widely deployed in less than a long time (if
not, sell your Sprint stock now ;-).  Please understand that I don't
much care for this idea either, but all of the arguments against it so
far seem at best lame.
