Not so much stepping on toes but late to the party; this was being
talked about on sugar-devel@ months ago, and we would not want to
waste the work done so far.

I'm curious as to what you mean by native Android. You mean Java?
The big advantage of rewriting from Sugar in Python to Sugar in HTML
is that the execution platform widens to cover both Android and
personal computer operating systems, with a single source code base.
I don't see how a rewrite in Java using the Android Software
Development Kit would help with that.
I have seen adequate performance of Sugar in HTML activities so far,
and in some cases better performance than Sugar in Python activities.

Your assumption about feasibility is easily challenged; we do not have
as many kernel maintainers now as we had before, so our history is not
a reliable indicator.

I don't see how licensing is relevant to the technical problem at
hand, but the Sugar in HTML activities seen so far have been open

No, laptops are much less likely to be distributed secured now. It
depends on the deployment what they choose, and they have to be able
to sustain the necessary technical effort before they choose secured
No, licensing is still relevant to end users, regardless of whether
the laptops are secured. But OLPCs main customers are the deployment
teams, rather than the end users.

Yes, I see you are criticising. ;-)
