I've seen many people draw strangely shaped buildings during mapathons,
always with a mouse. It is more a matter of interpreting satellite pictures
than anything else. For example, understanding the difference between a
shadow and the building, or following the outline of the roof instead of
the ground imprint.

available tags in ID from the Tasking Manager task setup manager. There
would have to be some kind of warning in the editor though; something like
"This is a limited version. If you want to be able to add things not asked
in this task, click here to break out".
