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

Yes - it would be difficult to detect things in webkit/xulrunner. Also
it won't work for Scratch or Etoys. I think for such cases, having a
dbus service from sugar to show/hide the keyboard may be a good idea
(at least some activities may be able to take advantage of it)

Sounds like a good idea.
