Lazyweb: Router/WiFi/Streaming Video/DVD Player

[jesse_the_k]

Our current home entertainment system is cobbled from three decades worth of high tech, and the edges are starting to fray. Right now I have almost a dozen individual pieces, and I'd like to downsize in replacemnt. All the streaming gizmos -- Apple TV, Roku, Boxee -- do some of what I want.

My Ideal Magic Box would
bring internet in on coaxial cable
provide internet programming to the HDTV via Ethernet
create a wifi signal for the house
play music CDs and DVDs (Bluray if it's required)
provide an over-the-air FM/AM tuner
connect to a bunch of speakers

How come the sort of tools I found at Netflix "streaming hardware list" never include a wi-fi router?
