And a potential answer that had to be written as a comment because Tester101 closed the question so early:

Lots of options ... 1) Convert to awning or casement windows, then motorize the crank. 2) look into mechanisms that automatically open/close greenhouse windows. 3) look into motorized skylight hardware. 4) make a box-bay window, reusing the slider and making the side lights or top/bottom open-able. 5) replace the stationary sash with a motorized something or another that does no obstruct the movement of the slider.

I think this sort of overzealous moderation is hurting the site, not helping it. DIY stands for "Do It Yourself", which will sometimes necessitate creative solutions. Other Stack Exchange sites, Stack Overflow especially, are based on novel solutions to specific problems.
