I'm afraid we do that, too. We call ours 'sharedassemblies', and it's for those little things like Excentrics World's stuff and MetaBuilders. Too many people to coordinate downloads and reinstalls, much easier to point them to a shared location and be done with it.
Somehow, I'm embarrased of it. Not sure why.
But then, I've never used the phrase, 'easy peasy', so perhaps I've nothing to be ashamed of...
