Ppointer

Ppointer allows you to control multiple presentations on different computers. Once those computers are connected on the same network you can control your presentations on all computers. The commands work outside of power point as well if you want to use it. You can download the client via http://www.igestdevelopment.com/ppointer_description.html. The client is executable and just runs. Wherever the client is running and connected to the server (app on phone) you can control that computer (powerpoint).
