I wonder if this means Google's QUIC protocol is dead in the water, since it works over UDP.

You can basically have bigger UDP packets, that will get fragmented and may not make it to their end.

As far as I know, in Linux there is no support for multi-packet UDP vectored I/O. I wonder if it would be possible to "simulate" that with a raw socket....
