If you are just streaming local content, that is media stored on your iPad, then yes it will work. If you are trying to use the mirroring feature, same rules apply. You only need the internet if you are trying to stream internet content via airplay or mirroring.

No. Air Play uses homesharing. If you are not connected to the internet then the devices will not see each other. I run into this problem when my router occasionally hiccups and has to be reset. The internet connection is down and there is no connection to homesharing through the ITMS servers. My iPhone, iPad and MacBook Pro will not see each other, not even for streaming local content to my Apple TV. Plus, just because something is stored locally does not mean that an internet connection is not necessary to view or listen to it. If it was purchased from ITMS then you must be able to connect to verify legitimacy to use content. Without that verification iTunes, Quicktime, or the Apple TV cannot decode and play the media.

AirPlay doesn't use homesharing.
