p.s.

As for the version byte vs minor/major scheme discussion. Why not
simply declare that we will always be backwards compatible, and
only ever add new fields ? Then we can simply add version checks
around those new fields, and have both back and forward compatibility.

In this case the single byte should suffice nicely.
