Tonight the iOS 5.0.1 update arrived, which means a chance to test the new over-the-air update system introduced in iOS 5. Over-the-air updates are one of the most important sanity-saving features of iOS 5 for people managing large installs of iOS devices. Instead of having to connect to iTunes, download a 700MB+ restore image and connect your iPads one by one, you can install the update directly on the device.

Speirs' site is a great resource for folks managing iOS deployments... At Lewis, we have 70 iPads in use in our 4th and 5th grade classrooms. Over winter break we plan to do the upgrade from iOS 4 to iOS 5. Once this is done, then we can take advantage of Over the Air (OTR) upgrades.
