The argument for doing XEP-0047 now is this is how Cryptocat implemented
their file transfer, so we could be exchanging files with them faster.

Also, other apps support XEP-0047 (Gajim and pidgin off the top of my
head), so we could do non-encrypted file transfer with them.

However: I think a transport layer agnostic  (aka pure OTR) version is
incredibly useful+important. And since doing pure OTR will be faster to
implement, I'm for that way first.
