how about a map like this one that several users can update.

hey steve,

glad to see that you got this project going.
I had mentioned something like this a few months back.

a great site to use as a model for this is http://www.chicagocrime.org/

w the open api of Google Maps, you can create great 'mash up' sites just like that.

good start Steve!

would be happy to contribute other ideas.
