This is a great short summary, followed by the Tech Talk (on youtube) which goes into a bit more depth about the how and why of the design considerations. What isn't mentioned is basically, because the change is 10KLoC to the kernel (unprecedentedly huge change for just the functionality they added) it hasn't even been submitted yet, and mainline hasn't even considered it yet. I'd love to see it hit mainline, or parts of it start getting submitted, but the biggest thing will probably be re-writing the whole thing to have a much smaller impact on the kernel, while still providing the functionality they need (e.g. use the TCP backoff instead of their own, etc).
