Chameleon 1.0 (final release) will have functionality to draw features, or
'footprints' based on geographic coordinates.  Building an interface to do
that would involve a custom widget of some sort, but yes, it can be done.

I can't speak to the moving vertices type functionality.  That would take
some major additional DHTML.
