Ignoring for the moment that those directories aren't quite right (close 
enough), the shared bits on linux are a bit problematic. Some installer would 
have to put them there, I guess the package manager if thats how the game was 
installed. Normally a user wouldn't have permissions to make such a shared 
folder. It has to be someone with root/super-user permissions.

That and I don't know of a standard shared, rw location, other than $TEMP.
