Just to clarify:
1. OLPC-A's intention is to create a HTML5+JS  framework for creating
Sugar Activities.
2. Sugar Activities created using this framework will run equally well
on both 'Sugar for linux' and Android.
3. This requires two separate abstraction layers "wrapper" one for
Sugar on linux and one for Android.
4. These abstraction layers make Sugar Services such as collaboration
and the journal available within the HTML5+JS framework.

Is there an implementation plan and roadmap available? Are there
sufficient resources committed to these projects to see them through
to completion?
