[Mesh] Layer 4 roaming?

Some of us had recently been talking about Layer 2 vs. Layer 3 roaming. Well, it looks like HTTP/3 is basically a TCP replacement on top of UDP, and it allows a connection to continue between IP address changes by using a per-connection UUID. https://blog.erratasec.com/2018/11/some-notes-about-http3.html We can expect this to be implemented, at the very least, in the most popular web browsers but possible other programs as well. This could really mitigate the issues with non-roaming capable mesh networks. -- marc/juul
