Hi!

But couldn't the packet format be made so that unknown values in there
are simply ignored? And also ignore unknown packet types? So that at
least connectivity is possible, but not as good as it could be? For
example, if we have some node which reconnects after a month, it would
be great that it still is able to connect, so that we can at least
upgrade it.

And it would also see all nodes as directly connected together? So:

[nodeA] --- [tunA on server, tunB on server] --- [nodeB]

If I bridge tunA and tunB together, nodeA will think that there is
only one hop to nodeB, no?
