I am sending my third and final message of the day, in order to express
support for Hadmut's suggestion of a binary encoding. I think this is a
good idea, and I believe it combines the best of various worlds
(extensibility, economy, etc).
Quick sanity check: Any preliminary measures on the savings in such a
format?
I did a couple checks, but because we're dealing with basically textual
information (domain labels) and such small packets, not much is saved in
encoding the non-domain-label information more tightly, and gzip is
ineffective on such small blocks. Even the XML overhead didn't affect it
much.
