Here's a few links related to the OpenLab's eKo:

I get the impression that Open Labs is looking for venture capital to go into production with but their keyboards may not yet be ready for ordering. It is certainly a cool concept that is generating a lot of buzz. I don't necessarily see this as a threat to keyboad manufacturers though - they'll probably adapt their products to run as softsynths eventually.
