That sounds great. I always wanted to have something like that!

I have some thoughts about it - not meant to criticize, I'm really looking forward to seeing this used more widely!

* Are "private" messages really "private" in the senses that only the user logged in as the recipient will receive them? If not, maybe rename to "directed messages" or so.

* If this catches on, there will soon be demand for some kind of authentication - that keeps me from joining the chat under the name "Zverik" or so ;) maybe it could be implemented with OAuth, where the server would check with the OSM server whether the logged-in user has the same user name in OSM, and then notifies clients whether a certain user name is "authenticated" or not. People could still use any name but clients could make them show up in grey or so if they're not authenticated.

* I don't yet understand how messages are located. You seem to be using point coordinates only, so if i write something is that always mapped to the centre of my curren viewpoint? If I zoom out and have a 50x50km area on my screen, will I only see the messages pertaining to a 20km circle in the middle of my screen? - I have a feeling that maybe the plugin and protocol might benefit from extending this to use rectangles in sending as well as polling for messages.

* Auto-login for the plugin would be great.

* Maybe announce on JOSM's "message of the day" to get more people to try it out?

Great work!

Bye
Frederik
