Ah, nice!

Feel free to post a patch (series) here when you feel up to it and I'll offer
you by comments/review.

Do you think it makes sense to also support some sort of proxy protocol
prefix? Like for example setting the proxy to "turn://IP:port" in the same
vein we can do SOCKS and HTTP etc already. It makes it way simpler for
applications that want to pass on or set "a proxy".

Is there perhaps any other existing clients/browsers that support TURN that we
can learn or adapt config ways from?

For someone not really versed in the details of the protocol, what's the
actual protocol differences between short term and long term auth?

If you make it like the socks proxy approach, can't you just add a function
call in ftp.c:proxy_magic() then to make PASV work?
