Can you explain Mew? I can already install, update, and even configure plugins AND skins from within MP using the Extensions plugin (companion to MPEI). Of course, it only works for plugins and skins that support MPEI but most do already and IIRC, TV Series soon will. So far, I still need to reload MP for the new extension/update/conifg to take effect, but I believe Dukus is working on that! Also, there is an Update Control plugin that can track Windows Updates for you and alert you. I am not sure about add/remove components in Windows, but I doubt it.Having plugins such as TV Series and Moving Pictures as addons means that their development cycle and times are not tied to MediaPortal Releases. It would be nice to be able to install plugins from within MediaPortal, and say, to be alerted to updates (like where you can add or remove components in Windows and be alerted to Windows updates). I guess this may be possible in MediaPortal 2 and I assume the respositories (for plugins, skins etc.) on the redesigned web site might aid this.

I don't think we will ever see plugins like Mov Pics and TV Series included in MP, even in MP 2. As you said, it gives them much more freedom if they are not. We get many more features more quickly when they are separate. Besides, I have never heard of any of those developers wishing or requesting to become part of MP.
IMO what we need is a way to install extensions as part of the MP installation process - a kind of front end for MPEI that fits into our installer. In fact all we really lack to do this now is a GUI interface for MPEI that could fit into the Installer. But I don't know if that will happen for MP 1.
