The Wireless G Music Bridge connects to any home entertainment system or powered speakers, and uses its own drivers to pipe audio from your PC to the sound system over WiFi. According to Linksys, the $99 device will work with any audio source on your PC. Linksys is currently pitching the Music Bridge in partnership with Yahoo, as the perfect "complement Yahoo's digital music download service," which means you can get a $20 rebate if you join Yahoo's music service for a year and buy the Music Bridge.
