Stage Manager
For Stage Hand to work, you'll need a small helper application, Stage Manager, running on your Macintosh. Stage Manager is how you give permission to iPhone or iPod Touch devices to control your presentations.
Stage Manager also includes a Wireless Signal Tester, to check the approximate speed and quality of your network.
This is completely free, and you can download it here:
Stage Manager requires Mac OS X 10.5 ("Leopard").
