Ah yes, I see. I just misread the instructions on the packaging.

It might be worth packaging for Debian at some point; would you like me 
to give this a go at some point? Separate .diff.gz(s), probably. This 
might require some changes to the structure of the source bundle.

http://library.gnome.org/devel/goocanvas/unstable/goocanvas-goocanvasitem.html#GooCanvasItem--visibility

might be of some use here. As for making objects editable, that's 
handled in osm2go's code and could be quite easily overridden based on 
the zoom.
