Comment (by cohosh):

 Replying to [comment:3 cohosh]:
 > My next step will be to look at the pion STUN library and see whether
 they support this feature/how to use it for our purposes.

 Looks like this is unsupported at the moment, but there is an
 [https://github.com/pion/stun/issues/8 open issue] for it and this RFC is
 referenced in their README. It wouldn't be an unreasonable task for us to
 implement this and submit a PR. We've had these PRs merged very quickly in
 the past.
