AOL Developing Cheap Switch for Audio Streaming

legaleagll writes: "According to a Fortune magazine article and a follow-up article on ZDNet, AOL is developing a cheap switch that can handle streaming audio for 10,000 users, versus current technology of 100 - 1,000 users per box depending on expense of system. The code name for the product is Ultravox and was apparantly spurred into existence because RealNetworks is now offering internet service for cheaper than AOL. I'm a little skeptical because I'm not sure how the use of an intelligent router would eliminate the need for the expensive systems to stream the audio. Wouldn't moving the software for streaming onto the router make for a more expensive router and still require the expense a box outside of the router anyway?"
