Umm... this seems to be a confusion between what you would like to be true
and what is true. You and I have certainly had conversations about IMPP in
which you have said that we'll need "HTTP over UDP", and you might yet turn
out to be right. But there is absolutely, positively no work in IMPP right
now that has to do with "HTTP over UDP". (There's nothing that has yet
ruled it out, either -- but it seems like a stretch to say that IMPP "had
to do work on it" just because we haven't forbidden it).
