As it stands, it seems the only real demand for ultra-highspeed (40Gb/s+) is in the data centers of the facebooks and googles of the world trying to shuffle around all the data between their own servers. I don't think the average home user really cares about moving around petabytes of metadata around a network so I can't really come up with any ideas based on exisiting needs for such speed. Other than multiple HD streams and telepresence type stuff I am at a loss for ideas that don't completely ignore efficiency of the traffic. Certainly, I can saturate a 1Gbps link, but I can typically do the same with less bandwidth. You'll probably see a lot more of consumer cloud based computing and such assuming the latency and whatnot is also solved in the process.
