Can I tether 3-5 professional DSLR's simultaneously to one computer into one session?

I am trying to tether 3 cameras to one capture station for simultaneous capture.  This will be for animated "stereo" photos, freezing motion, so it needs to be simultaneous.  Can I do this all in C1 or do I need a 3rd party software?  Any advice on how to accomplish this and any tricks/fixes would be greatly appreciated!
