Hypersonic Sound Laser For Sale on eBay

If you are interested in buying that mega-cool sound laser beam, Boing Boing says one of them is now selling on eBay. The starting bid was $800, it now (10 am CST Monday) has reached $1825. But, "DO NOT BID on this auction if you plan to [...] use the unit for abruptive advertising (to traffic or people passing by your store/billboard/etc)." Can we use it for non-abruptive advertising, thank you very much?
