The proper architectural solution is to place network layer
information like what is being proposed in the network layer :-)
Trying to make a network layer out of UDP fails on several accounts
(fragments don't contain UDP headers, ports do not have global
meaning, etc.). IPv6 extension headers are designed for carrying
information like this, I really hope there is more investigation as to
whether they are workable for signaling.
