I wonder how MeeGo is supposed to be able to fulfil that. From speaking with Intel reps one of the key features of meego is security (which defintely is a point where maemo is extremely weak). And in order to protect the users content from malicious apps but also to implement DRM/content protection, they plan to install a crypto/authentication framework.

However, i see two problems in doing that:

a) the GPLv3 (which MeeGo imho uses with gstreamer) prevents you from using encryption to protect your business modell. How is this supposed to work?

b) Of course such a framework limits the hackability. A device cannot be completely open on one side and protect user data as well as multimedia content on the other side.

So will we have to jailbreak the next gen devices? Will the average user still have a method to get root access without removing/lossing vital parts?

This sounds like the same problem Sony solves on the PS3 by removing the "OtherOS" option: You cannot allow people to openly tinker with a unit that carries information that you don't want them to tinker with.
