ICE is clearly the best solution as it handles NAT, security (peer
verification) and allows IPv4/IPv6 transition. SIP endpoints *MUST*
implement it or continue working in vendors wallen gardens. Bad luck
for them.

But creating a new spec (as you suggest) just to allow lazy SIP
vendors (those who has never cared about security) to interoperate
with RTCweb world instead on forcing them to implement ICE is IMHO a
very bad idea.

SIP vendors MUST do their homeworks. ICE and SRTP were initially
designed for SIP. So SIP devices MUST implement them.
