Ad-hoc/Local multiplayer

Hello,

I'm currently working on a small game that is basically players throwing weapons at each other.

I would like to be able to get local multiplayer working on the Vita. I know it has ad-hoc, which enables games to have multiplayer.

My question is, do I need to program the game as if I was to do online networking, with syncing variables and host/client stuff or is local/wifi multiplayer simpler than that?

Does anyone have any experience with ad-hoc in Unity?

I appreciate anyone's comments/information/advice.

Thanks.

Keith
