Arc-fault Circuit Interrupters

Got a few questions concerning this new technology...

How do they work?

How much will they cost?

Why does the NEC think that arcs only happen in bedroom receptacles? (Or realistically, why the requirement for bedrooms over any other part of the house?)

Why not protect every non-dedicated circuit with one? (probably cost prohibitive)

Should I start installing them in new dwellings now, or wait til 2002?
