I'd suggest we could access the tree of a mossm alive (being ours or not), clicking on it. Ours we can check on our dashboard but its not what happen when its not ours :D

Stats transmitters do what you are asking for. Just rez one on your land and all mossm stats are visible to whomever clicks them. You can get one here: http://mossms.com/content/live_selling/

This is a voluntary thing of course. Some people don't like all the local spam so we leave it up to individual users.
