Ok, have any of you seen this design?

http://www.cyclingnews.com/tech.php?id=tech/2008/features/truvativ_hammerschmidti08

Picture this with an internal hub on the back of a touring bike? There
wouldn't be a need for deraileurs and therefore no chain tensioning.
(you'd need horizontal drop outs of course). heck would you even need
a chain, can you go with that belt design that I've seen out there? No
more cleaning and lubing a chain!!! No worry about snow / ice, road
grim, etc? Am I dreaming or is this a real possibility? Or do you
already have enough ratios with a Rolhoff? What about with a Nexus or
Alfine internal hub? Does it get you closer to the rolhoff for less
dollars?

I have yet to sit down and put the numbers into excel and figure out
the ratios, but it the front is a 22 and you get a 1 - 1.6 that gives
you an effective 35 front. Go a little larger like start with a 30 and
you have a 48 / 30. Now I've got to see what the effective ratios are
for internal hubs (rolhoff and alfine?) There may be too far of a
spread. If those gears are quite close (ie. 15, 16, 17, 18 rear
cassette one tooth spacing) then this starts to make sense. If the
ratios are large then it doesn't because you don't get anywhere.

What else am I missing?
