BMX Style Stem For A Road / Track Bike?

More fascinating goodies from the Blue Lug blog. 

You've seen in the videos how some of  the Japanese dudes are already rocking BMX bars in their track bikes, right? 

However, putting a standard old school BMX stem (which IMHO generally look pretty cool) in a road bike frame/ threaded fork shouldn't work as they are different size standards, and same goes for BMX bars and road stems, but now there appears to be a BMX-styled stem in normal road/track bike size. Apparently. It looks kinda neat. I want one.
