Exactely the same here (except for the pony, give me a flying car).
A multihead machine, where plugging an input device on a user's monitor
automatically grant's ownership to the right person (HAL magic ?) and
where windows can be shared.

The "SD attached to multiple MDs" thing confuses me though, what's the
use case of that ? Also giving focus to "unowned" keyboards looks
useless, unless the WM knows about them and let them cycle through
windows with an alt-tab-like sequence.
