Hi,As I said in the meeting, we have an implementation of this (the basic encapsulation, not the SDP signalling), and I support it's publication as an experimental RFC. I have two suggestions for modifications, though:
1) I'd recommend registering a UDP port for the DCCP-in-UDP encapsulation service.
2) I suggest the SDP extension be changed to be a declarative "I support DCCP-in-UDP NAT encapsulation" option, rather than listing preferences or ports.
Both these are in the spirit of doing the simplest possible thing that could work.
I'm happy to contribute text to the draft for these, if the group accepts the idea.
