For the sake of history, Christer suggested using connection:new with DTLS
in offer/answer. Paul asked if this is "strategic" enough. I sent the
response that strategic solution would be to fix DTLS/ICE combo and make it
a single multi-path secure protocol. If needed, I can try to write a draft
for such protocol which combines DTLS and ICE functionality. This is not
the hard part. The hard part is convincing others (primarily browser
vendors) that they should adopt this. So, if anybody is interested in such
new protocol, let me know. Otherwise I would shut up and wait for ICE/DTLS
problems either get resolved or become so bad that the new protocol would
be unavoidable.
