It would be really neat if this could be used with Google Streetview. Another cool addition would be an accelerometer on the handlebars to enable steering (though I guess that would be problematic with a stationary bike).

I initially connect up an arduino, but then moved to ant+ protocol over a dongle. . The biggest problem is the refresh rates arent good enough on Streetview for proper cycling - plus the usage on google maps was high - so i ditched it
I've heard several recommendations to integrate this with Streetview, but IMO the resolution necessary for moving in small increments isn't there. It's much better served with a 3D environment.
When I see the words "trivial," I think of a weekend project - not something that would involve tons of man hours.
