Dismissing the keyboard overlay when a text field is defocused would also be ideal.

FWIW: There is no global system gesture or button on the iPad for revealing the virtual keyboard. Selecting any text widget will reveal it; app developers can programatically reveal it (say if they have a custom canvas, our Labyrinth activity would fall in this category); a few individual apps from 3rd parties (none I can see from Apple) have added their own floating semi transparent keyboard icon usually in the far lower right screen corner, in one case (a text chat app) this just seems like poor design, in the others I can remember it's for cases where there is no sane way to know if the keyboard is needed (VNC, RDP clients).
There are no keyboard only iOS devices, and all app developers knew from day 1 that devices were touch only, so we are in a slightly different position with needing to support both key and keyless devices, and activities that were written without touch input in mind... So I'm sure we will need a fallback button. Sayamindu device frame seems a good choice, once we have a touch gesture to reveal the frame that is ;)
Anyone know what the planned physical buttons may be for the XO-3? If Sugar was native on iPad hardware, I'd certainly want the single home button to reveal the frame, with perhaps a double click of it switching to the Sugar favourites ring view.
