Getting an app on two iPads in sync

We are trying to fi开发者_JS百科gure out a way to get app on two iPads in sync.

So the use case would be like this:

We have two iPads, on each one is the app A running. User 1 is doing something on his iPad and this changes should be displayed on the iPad of the User 2.

Do you think a bluetooth(WiFi?) communication could work or should something like a VNC viewer be done?

cheers

If you only want to sync them on local wifi or bluetooth, without using the server, check out GameKit peer to peer. There's even sample code from Apple that shows you how to pair devices and communicate between them.
