I tackled this problem with a history manager and the hash. So a user could actually bookmark a particular page or open a link directly by middle clicking and associate some javascript with a particular hash. It has worked extremely well thus far and the project that I did this on should launch soon. I based the history manager on the unFocus History Keeper. I will publish the work soon ... just haven't had time.

I doubt the inventors of "open in tab" and "open in new window" could foresee these issues.
