Wonder how this would work for younger kids. If It doesn't, then you can't do it, since you need to have all of the kids in 'school' the same number of days.
If it did work, I wonder if it would work for a county like mine. A little background. We are a fairly big and varied terrain county about 45 min west of DC. We have horrible snow removal, so there are some strange days called off. (They do build in 15 days into the school calendar by counting hours instead of days as needed, so by making each day longer and not extending the year in June.) There are some days that are fine in one part of the county and not in the other, but they have to call the whole county to keep every one even. In theory if this worked, you could call the part of the county that was hurt by the storm more, and have those students work from home. You might get some P.O.'d students, but such is life.
I believe the schools should provide each student with a 'loaner' computer, so everyone is working from the same level. Maybe you could get a wireless company to provide internet.
