I'm probably not the only one, but I have no idea where the separation between Chromium and Chrome actually is. Can anyone enlighten me as to where the separation really is? Is Chrome a fork of Chromium, is Chromium an upstream? I know they actively work together in a lot of ways but how exactly?
Aside from the obvious - branding and stability - It's mainly the commercial stuff (MP3, PDF, Flash) which can't be distributed under Chromium's license.
