Yeah.
We have this problem in many places: webrtc, IKE and a bunch of other places.
We really need a system call that says:
"pretend to send this packet to target X, and tell me what source IP you'd
use"
Otherwise, applications wind up having to read all the interfaces and all the
ipv4,ipv6 and the ip rules, etc. and emulate all of the kernel stuff. It's
impossible.
