MPTCP can have lots of implications, which is what I talked about at
Ausnog 2 years ago.

"The Rapid Rise of the Mobile Multihomed Host, and What It Might Mean
to the Network"

As somebody mentioned, Apple deployed it in IOS 7, a week after I did
that presentation. Apple are using it for Siri.

In the last year or so I've seen a Facebook kernel engineer job
advertisement which listed experience with MPTCP as desirable, so I
think that is a bit of an indication that they may deploy it at some
point, although there needs to be handset support for it. Hopefully
Google will put support for it into Android in the fairly near future.
