Great possible joint venture idea. Medical clinic takes advantage of great foot traffic, accessible location, and Wal-Mart adds another reason to shop (think of family members waiting for the patient to get checked out; why not shop while we wait?).

The big challenge is margins which get tighter and tighter. If Wal-Mart can take advantage of their size to negotiate better pricing then it could work.

With the new health care initiate in Congress, this could all be out the window pretty quickly though - high risk, low reward.

Outside of the healthcare angle though this has some nice applications for businesses with excess store space capacity and dropping revenues - bring in compatible JV partners and share the profits - win/win until things turn around.
