remember rox? (Score 1)

Remember Rox Desktop? http://en.wikipedia.org/wiki/ROX_Desktop Very similar to how mac os works. Lay down a base system with the common libraries in a central location. Apps are just custom folders with a very specific directory structure. It's not horrible, as an end user it's kind of nice. It will lead to security whack-a-mole issues when common but non-core libs have issues, but nothing's perfect.
