actually we had the same problem with keyboard layouts until I discovered a solution...if you're using Windows as your workstation (I'm sure you can do the same thing for Linux workstations, too, I just don't know how) you can go into the Control Panel and hit the Keyboard icon. From there you can add new layouts from the Input Locales tab. So add either Dvokak or Qwerty depending on what you don't have.

Once you're done, at the bottom of the "Input Locales" is a hot key selection which allows you to switch layouts on the fly on a per-window basis. So my partner and I often switch and hit Left Alt+Shift to switch between layouts on our terminal windows. It makes pair programming much easier.
