There is lots of stuff that could be the next great thing, and then you never hear about it again. One of the chips I worked on at Globespan-Virata was a 4 channel 100 Mbps DSL router. So the phone companies could run fiber to an apartment building or office building, and support four 100 Mbps internet channels. Or bond the channels and have one 400 MBps internet channel. I did the verification of the design and it actually worked perfectly in the first silicon! (That was almost unheard of for such a complex design at the time.)
I went on to Rockwell when they bought my division, and then got laid off a year later. Never heard a thing about the chip after that. Such is tech.
