oops, nvm the part about the link ( I was thinking a link with the map so you could view it in flickr). I hadn't realized that the image already was a link.
You can have multiple users in a single DOMA each with a seperate login. It's a handy service for people and an easy way to see each others maps. It also has the advantage that people wouldn't need to find their own host servers. See
here for a nice example.
