Kirk -- The short answer is sorry no. No provisions for multiple cameras and no provision for earth orbit objects.

The biggest barrier is the multiple imaging systems. ACP relies on MaxIm DL for its imaging (this could change, but the chances are remote at present), and only one MaxIm can run on a system. You might be able to create a system like the AAVSO APASS system. It uses a master-slave system with a second system driving the second camera as a slave to the first.

The addition of earth orbit would also be huge as the User Interface is completely different in its character.

I'm afraid I need to pass on this.
