Quite an interesting idea, but they look to be a long ways off from useable.
The skeleton looks too rigid (ask Canondale for 'engineered flex' ideas) to offer any sort of grip or cushioning and then there is that slight problem with mud (or cow crap for us). I don't think the super tacky stuff would fling out the small slits at the tread.
Make some 2.5's with the grip of my WTB Prowler MX's and I'll try it out.
