Setting up community map

Hi

I am thinking that someone might have already done this with a collection of different plugins, but would be grateful for any ideas.

I am looking to set up a map which shows a number of local businesses. These pins on the map will be generated from listings, a set of WP_Posts.

The key thing however is that all WP Posts will be generated by users. They will register, their login will be moderated and then they will be able to add their own listing. This listing will include Name, Description and a Map coordinate as well. Once moderated this will appear on the community map.

When they login they will only be able to edit their own listing.

Basically, most of the functions can be done using WP Geo Mashup, but I can’t find a membership/registration plugin that interfaces well with it.

Any ideas would be greatly appreciated.
