This is getting off topic, but in helping my advisor prepare an invited talk a few months ago I found that the idea of cross-talk canceling was invented by Manfred Schroeder and Bishnu Atal in the 60's at Bell Labs: http://www.freepatentsonline.com/3236949.html
They should have waited 40 years to apply for that patent! The more recent work that I know of has been done by Darren Ward & Gary Elko, Chris Kyriakakis' group, and Kirkeby & Nelson. I'd be surprised if there weren't a couple of vsts, but I don't know of any off hand.
