Well sharpness is one of the thing I personally care. :-)
The websites like 'PZ' which provides data on sharpness are pretty useful to come to any decision before I buy a lens or two, but in many instance I do not own the body which they use for those test and in that case, it will be very interesting to acquire the sharpness data by myself.
I may be ignorant that sharpness does not depend upon camera body, but I do not know that yet.

Sharpness does not depend on camera body. If a lens is sharper than other lenses, tested on a particular camera body, then lens will also be sharper than others when put on different camera bodies.
The only "exception" is lenses tested on APS-C, you can not be certain how those lenses will perform on full frame 135 format, as on APS-C the edges are not used, and on full frame they are.
