UDP was designed to be used for experimental transports like the one
suggested here.  Using something other than UDP as the basis for an
experimental protocol would almost certainly cause every router in the
world to drop your packets.  This is part of why SCTP isn't widely
supported.  There are a large number of protocols which essentially
implement their own transport on top of UDP.  RTP is one good example,
it implements features that it needs without incurring the full
overhead of TCP.
