Arnulf, Thanks for your message. I looked at the mapbender site, and it looks like it has the basic functions except the password protection, which you will probably need at some point:-) The performance from here (California) was slow, and the map image did not look as good as Google's. I suppose we have better map images available? I could not find Cunninghams talk on P2P style wiki's, but seems to me that it would be too much work for a simple web page. Ideally, we'd just want to have a static map with possibly Javascript popups. That way, the performance can be good and the web site doesn't become that onerous that the pg www group kicks us out. So, a question to you and Palo: Can you generate such static map (along with Javascript code) from Mapserver?
