Hi Mikkel,

I think this current protocol does not prevent you from doing that as it is
designed as a minimally-scoped extension of QUIC-v1. The goal is to make it
easier for people to try different things with multi-path. As pointed out
by Christian, announcing address/port/QoE does have some complexity. One
way is to let the client server cooperate, but you may also want to use a
STUN server to help you achieve that which is similar to the case of RTC.
We would appreciate it if you could try and let us know your experience.

Cheers,
Yunfei
