A cool new command would be /livemap. this would give players a link to the livemap. maybe there is another way but i haven't found it yet. just an idea . (there isn't a suggestion thread is there? i looked)
I think the cmd can be added to VentureChat. Also there's a broadcast link in the server along with the dynmap page up in the Gameservers tab in the forums. I'll see if I can add that cmd soon.
