That's a nice idea, but it only solves half the problem.

You also need to handle the case where you have use shifted arrow
to mark the region, and then use an unshifted arrow ... which should
deactivate the mark.

It seems like a simpler solution would be to have special events 
like <shift-down> <shift-up> <meta-down> <meta-up> etc....

A third possibility would be a "point moved" hook (at C level)
which was called with the original value of point - and the
original event modifiers.

BTW, cua-mode has some special code to detect the shift modifier on
a tty (something about looking for "S-" in the key symbol).
A solution should work equally well on all platforms!
