No. But I hadn't heard of this one... it sounds similar to how webrtc
works... I'd like to see udp more used... as there are plenty of
things that tcp does that aren't actually needed by a web interface
(in order packet delivery for example)

Ages ago I'd written a command line tool for searching google that
could do your basic search in a single packet in each direction. It is
very useful for doing research within emacs and org-mode in
particular.

regrettably the API I used is deprecated by google, although it still
seems to work (as does the bing api and a few others), and I killed
the single udp packet version of the protocol in an orgy of code
cleanup one misguided day thinking I'd add crypto (DTLS or pgp) to
it...

There has been also been work on sctp and multipath tcp. It's good to
keep banging the rocks together until something, anything, makes a
spark.
