And being lazy pay's off, no math involved.

P.J.,
Regarding the bandwidth of USB 2.0:
If USB 2.0 is sufficient for tethering Canon and Nikon DSLRs with live
view, why wouldn't it be sufficient for Pentax, whose sensor is similar
or smaller (pixel-wise, and hence bandwidth-wise).

The 645 was a studio or field camera, but I think the 645D is very much
seen as a field camera by Pentax. I also don't think that the imaging
sensor in the 645D even supports live view. The Hardware in the K-5 and
K20D might support Live View through the USB tether, however the
firmware doesn't. Maybe somebody has produced a hacked firmware version
that would allow them to work that way. I think that USB 2.0 probably
supports the bandwidth necessary, but I'm really too lazy to look up the
specifications and do the math today.
