Right. This discussion went well beoyond your use case.
We looked at the default case with todays hardware.
Here is what I have been saying all along:
We need more input from hardware vendors what we can
realistically expect in the future. Are E-Ink displays
(as much as I would like to have it) something that
is going to happen?
As long as hardware vendors don't talk to us until it
is too late ("We need to release a driver that can do
this and that by the end of next month") we can hardly
react and create an infrastrucutre.

Knowing that there will be a system with this feature
being deployed (the OLPC box) should provide sufficient
incentive to take this case into account in our design.
