Maybe this would be something useful for MMOs, or other server based games. I can't count the number of times I've died online because of terrible latency thanks to the connection my ISP had to the server. I honestly see this being the main port of call here. Thousands of connections using both UDP and TCP concrrently, the 30x improvement would definately help.

You're on a motorway and everyone is in big ass trucks. There's only 3 lanes either direction and traffic is grinding to a halt. One way to fix this problem is by widening the corridors and adding new lanes. But that's expensive takes a long time and expensive.
OR you can put in lights at every intersection, this will wind up slowing down traffic on all fronts, but it'll average out the speed. Good for those with terrible access, bad for those with great access.
You can tell everybody to get out of their trucks (TCP) and get on motorbikes (the new thing) congestion isn't as bad, no need for the traffic lights at every junction, and no expensive lanes being added.
If the road was clear though, hopping onto a motorbike would make no difference. And I see it being used to effectively lower running costs by these people. "lol, why should I buy the top of the line connection I need, when I can just buy this new transfer protocol, give people a crappy connection, and an easier way to use it"
