The obviously correct thing to do is transmit the key *hash* and only
send the full key if it is explicitly requested.  If buddy identity
means anything to you, you've got the full key stored locally anyway,
and you only need to transfer it *once* when the buddy is added the
first time.  sha-256 is only 32 bytes, almost a 20-fold reduction in
size.
