Yes, replacing caps lock with something more useful is the best solution for me:
I have left control there (and Esc on `real' left control). First is done by
ctrl:nocaps xkb option, second by line `keycode 37 = Escape' in ~/.Xmodmap (on
your machine number after `keycode' may differ).

Of course, this works only for X server. I don't know any windows or mac
solutions for this problem.
