seems like you could just use a cam and motor like in a Sea Sweep with stop switches for open and another for close.
Really sounds very simple.

One of the obsticales is then you must always use the electric opener as with a linear acuater. Does a tank sitter really want to go through the hastle of finding the way to open a cabinet door?

Make a forward/back button.

I'm thinking a spring to close the door and a pneumatic actuator to open it. You could use an apex outlet to power on an air pump to open the actuator and when off the spring would close the door.

A simple option for the air flow part would be a fan that vents air from under the stand.

Its 2am so I can't be heald responsible but how about a gear drive motor with a low rpm, atached to the shaft is an arm, attach to the arm is a linkage attached to the door. The motor will always spin the same direction, half of the rotation it will open the door, ther half it will close the door. I'm kinda thinking how the wheels work on a steam locomotive.
