I'd been thinking about this; collisions would only be a problem for 
plugins, and I'd imagined Blender assigning each plugin an ID in the 
order they are loaded, starting at 1 greater than the highest builtin 
ID. Then it writes a list of plugin filenames so it knows which plugin 
corresponds to which generated ID.

Using GUIDs here does have the advantage of plugin authors being able to 
change the filename of their plugin, or give two plugins the same name. 
I'm assuming your idea of using GUIDs is similar to the above, but 
replacing filenames with GUIDs stored in the plugin itself?

I'm not actually a fan of GUIDs; the fact that they're not absolutely 
guaranteed to be unique bothers me. But if they're the most practical 
option we have, I'm all for using them.
