I have now implemented all the corrections in the UDP encaps draft, except for

Indeed. I think there are three choices
* 6-tuple
* 4-tuple IP/UDP (with checks against conflicting DCCP connections)
* 4-tuple IP/DCCP (with checks against conflicting UDP ports at UDP
decapsulation point)
There have been arguments suspecting kernel implementation feasibility of
6-tuple. People have also wanted to see UDP tunneling work with unmodified DCCP
implementation. If I understand correctly this would be difficult with the
first two option. Would there be something wrong with the last option?
I think this is the only remaining open issue (right?). So let's try to reach a
conclusion. If you don't have clear favorite, is some of the options out of
question?

I vote for:
* 4-tuple IP/UDP (with checks against conflicting DCCP connections)
