Internet Exchanges supporting jumbo frames?

I would hazard a guess that reducing the packet header overhead *and* the Ethernet interframe gap time by a factor of 6 could make enough of an improvement to be quite noticeable when dealing with huge dataset transfers.

Then it's mainly TCP slowstart that you're trying to improve?
