[Tilesathome] Upload permissions for distributed server

Hm.

I'd say: Vandalism will be acted upon after an average of X people  
have seen it. Whatever X is; it will be about the same in Wikipedia  
and with us. Of course I can hide my vandalism deep down somewhere in  
a level-17 ocean tile. If nobody sees it, then it doesn't even hurt.  
And if people do see it, then it can be remedied.

Or the IP number in case of anonymous changes, right?

Nice ideas - have you seen the "Quadtiles" article on the wiki? It's  
a slightly different angle but seems to use the same underlying  
principle.

Bye
