XO has all these features.

This area is the most lacking area of the Dynabook. Pepsi,
Slate, Magritte, Seaside, Enlightenment[1], Sugar[2],
eToys, Scratch, Tweak, and Croquet are all partial solutions to
the problem, but they are all quite separate so far. This list
is clearly Squeak-biased, as I don't keep up with other
projects. I don't understand what you mean by "the UI sense", so
I cannot comment.

I think the hardware is ready, and OLPC does a great job of
uniting the hardware with secure AND extensible software. XO is
definitely the closest thing to the Dynabook that has yet been
created.
[1]: The Enlightenment Foundation Libraries are, in my opinion,
the only non-smalltalk graphic framework that can rival Morphic
and Tweak in the area of statically composable models, views,
and behavior. However, being C, it cannot really do post-load
composability. It allows composition all the way until
load-time.
[2]: Sugar, the XO default shell.
