It definately seems practical and potentially very beneficial over current testing methods.
Cost could be an issue.
SpotIR by research inc has a 250W model (not sure if you can tune the output or not, would think so, they have a range of products)

Still wondering on cost though...
Also would have to validate the wattage input and the black coating I think. Maybe get an insulated chunk of copper (known dimensions) paint bottom, and measure temp as a function of time to ensure what wattage is actually being absorbed by the block?
