There is a crude but very effective way. What you do is set both cameras to have an open shutter (used to be called B for bulb), set everything up the way you want it, open the cameras shutters and flash it manually with a flash unit. Since you have only one light source both will record at the same instant. This is controlling through the light rather than the shutter,

You need some method to actuate the shutter remotely.

Ideally, both cameras are identical, and have an input for remote shutter. Then its simply a matter of clamping them down, aiming them, and hooking the shutter releases together. Safest bet would be to use a double pole switch so each camera is actuated at the same time on a different circuit.

If you can't access a camera that has a dedicated shutter release, there is a firmware you can get called CHDK (canon hack development kit) that works on many canon point and shoots to allow usb voltage detect shutter release. Hook up a switch to 5v and plug into each camera's usb port - usb will trigger the picture.

Even simpler (yet more complex mechanically) is physically hitting both switches at the same time. There are cable releases to do this for many cameras - and an instructable on how to build one.

Post processing: Various programs can take in both pictures and make an analglyph.

A lot depends on what make / model of cameras you're using and how they would normally be remotely triggered. Check the manual. 
There's a lot of camera remote Instructables on here - Have a plough through and see which would be applicable to your camera, then modify to suit.  Modifying to double up the output should be quite easy in most cases.
