Aren't there any mac key combinations that allow you to resize or move windows without using the mouse? On a PC you can press Alt + spacebar, then S, and then use the cursor keys to move the top/bottom/left/right edges of the active window - even if they are beyond the boundaries of the desktop.
ETA: I don't know if this
free keyboard driven window mover for Mac OS X could be of any use?
