By far the best use of broadband for education is to support teachers who innovate. Most can't - thus the innovation barrier surrounding schools and keeping innovative technology out, including enlightened use of broadband.
Experiments in converting teachers into innovators have been extremely successful. One such program has thousands of teachers in it and they are clamoring for more technology so they can try their ideas out. But until they go through this fundamental transformation, teachers(and the school culture) will continue to resist technology, digital natives or not.
The suggestion: work with programs that convert teachers from "vertical" command-and-control overseers to "horizontal" empower-and-connect innovators. These teachers will provide, en mass, the essential ideas for broadband - they already are.
