You certainly will want only intermittent connections, then.

Good. If you are going to use that interface, I guess we should start using
the "version" field to keep everything interoperable.
Version is a 4-byte field.
I was thinking of making it:
struct version {
uint16_t major ;
uint16_t minor ;
}
With major changed when forward compatibility would be broken. (We'll try to
keep backward compatibility). Does this sound ok?
