The module plan is that you will be able to put your canvas in a module of your naming. Your app will be in that module, and within that module, you _could_ have global be an alias for that module. Thus, two different apps could be loaded in the same runtime and their 'global' would not collide. (Sort of how two swfs can be loaded into different _level's and not have their _root collide). For this reason, I think it might make sense to have canvas == global == (the user module).
How you would communicate between two apps is a separate discussion.
