I want to be able to access an iPad from a computer or 2nd iPad (either one). I dont care if the application requires me to be local (same network) or remote. Either will work.

I want to be able to access an iPad (that is connected to the clients wifi network) at a clients house so that i can close and open apps.

What is the easiest non jailbroken way to do this?

IF the jailbroken way to do this makes this significantly easier to do i might be interested.

Cost is not an issue here. I want the best/most reliable/easiest to use solution.

Thanks.
