Although I have not read the legislation that mandates use of RFC 4103
(and I'm not particularly interested in the Layer 8 issues), I don't
quite agree that one can't use SIP and XMPP in concert. For example,
one could use SIP to negotiate use of XMPP with XEP-0301 as the RTT
channel, similar to draft-sparks-simple-jabber-sessions from way back
in 2002:

http://tools.ietf.org/id/draft-sparks-simple-jabber-sessions-00.txt

That might not be palatable to the politicians, but it might be an
acceptable technical solution.
