Lee Morris over at Fstoppers has a great video that explains how you can tether your camera to an iPad wirelessly. This kind of connection allows you to transfer photos to the iPad as you shoot.
You would need to get an Eye-Fi card, either a Pro card or a connect X2.
The nice thing about it is that you don’t need to Jailbreak t
he iPad to create an Ad-Hoc wireless network. The new Eye-Fi card will do this for you and act as a router. (well, technically speaking it is not actually a router, but you get the point).
Sadly for mid range dSLRS (like the D300 that I shoot) it does not appear that Eye-Fi are going to release a CF version soon (or ever).
