iOS 4.3 for iPad to test new multitouch gestures, AirPlay video for Apps,

In addition to AirPlay video for apps (finally) it looks like Apple is considering new multitouch gestures for iPad with the just-released iOS 4.3 beta, perhaps to better compete with RIM's BlackBerry PlayBook and Android 3.0 Honeycomb:

Test Multi-Touch Gestures for iPad

This beta release contains a preview of new Multi-Touch gestures for iPad. You can use four or five fingers to pinch to the Home Screen; swipe up to reveal the multitasking bar; and swipe left or right between apps. We are providing this preview before releasing them to the public to understand how these gestures work with your apps. Test them and give us your feedback on the Apple Developer Forums.

Some of these might also match up nicely to the upcoming Mac OS X 10.7 Lion swipe between full screen apps functionality. What do you think, interested?

UPDATE: We've got an iOS 4.3 video walkthrough and screenshots up!
