[Standards] Re: [Standards-JIG] XEP0168 - UDP Sessions - AddUDPhandshake

[Thiago Camargo]

I agree, but, we can solve this.

RAW UDP transport is largely used as a unique way to transport.
Basically everyone that wants to use RAW UDP method, SHOULD provide a dynamic relay server.
The reason that people are refusing ICE and going to RAW, is because both exists.
My suggestion Peter is to unify Jingle transport in only one XEP with many candidate types. And add something more dynamic than static and defined ICE candidates.

Just a suggestion...

Right. Raw UDP is like the "I'm Feeling Lucky" button.
