Multipath TCP.

Multipath TCP.  I've been checking in on the multipath TCP project every once in a while over the past few years, as it promised to solve two problems I've run into: using multiple slow channels (like 56k modems) in parallel for increased performance, and transparently maintaining TCP connections across access point hand-offs (as occur in WiFi and cell phones).  I've been hoping that on some fine day it would be supported in mainstream products.  I just discovered that Apple's iOS 7, released just last week, includes it.  That's the first large-scale deployment of multipath TCP.  Woo hoo!  Now I'm hoping it appears in OS X in the next version or two...
