Looks like passing it to the objects as an argument is the preffered solution. My only issue with that is that I have a relatively large object hierarchy, with something similar to the following objects:

A instantiates B and C
B instantiates D
D instantiates E
[...]

So now if E needs access to the config module I'll have to pass it all the way down.

Yes, passing is slightly more typing, but if you don't, then you're accessing a global variable -- which is worse? The following might shed a little light

Why Singletons are Evil - Being Scott Densmore - Site Home - MSDN Blogs , Use your singletons wisely ; Know when to use singletons, and when to leave them behind

So a global app configuration is common use of a singleton ... I've used it, I've seen it used ... I don't really have an informed opinion :)
