Zeroshift. What happened?
Discussion
Is this system similar in nature to that of the Porsche Carrera GT?
I suppose it could be fully hydraulic, or one of those twin cone rubberbelt type systems.
I suppose the cynic in me says that there havn't really been many obvious developments in automotive transmission in the last twenty years.
Since the Carrera GT system was only announced a year or so ago, it's quite possible that it's a hybrid of that system.
Edited to add;
I've just read a bit more of their webpage, and it looks like it's a standard crash box, with an independent means of keeping the free gears spinning. Presumably it uses a "fly by wire" throttle, clutch and gearstick.

that would suggest it's blinking good then and will be worth the wait
Williams had some form of CVT in the mid 90's. Probably 93 / 94 before all the gizmos were removed. Saw some footage from silverstone where the car accelerated away then stayed at optimum RPM for the whole lap. It was banned before it was raced.
well i've just finished reading the article and all i can say is "wow" i'm well impressed with the design of the system and whilst reading gives half the story they show graphs of different cars changing from first to second gear and the final one is of the cerbera 4.2 with zeroshift, so impressive, its nearly a flat acceleration curve

Are you sure this was Zeroshift technology though? As its been strongly suspected that a few teams have been running a Dual clutch system / DSG ? Mclaren and ferrari to name a couple

Seems that they've had so much interest from people offering them money they don't need to start selling 'boxes to get a cash flow. They are planning a 6 speed aftermarket T5 (T56?) box for 2006.
This is all jolly good, but is it going to be available retro fit? (for instance G50's)
Last time I checked their site they were also asking for people to suggest boxes to work on.
As for retrofitting to an existing box - it works by a specially shaped dog on a dog 'box and uses springs rather than a direct mechanical link to the shift mechanism.
However, when just changing the box, as the n+1 gear overrides the nth gear, you suddenly have a lot of inertia in the engine that doesn't disappear instantly so you actually get an extra surge of acceleration after the change. Zeroshift are working on electronic systems to smooth this out, but this is obviously going to be a bit more complicated than just switching out a box.
