Althought streaming isnt lightening quick with the 360 and Vista Home Premium.

Keep in mind that this solution maxes out at a theoretical 14 Mbps. In addition, the Netgear ships with a 10BaseT ethernet port, further limiting bandwidth to 10Mbps.

This is not enough to stream standard definition content let alone high definition content.

It might be enough to play Xbox Live games on though. But I would suggest a Wireless G network over power line networking personally.

EDIT:
I'm looking into doing something similar to the OP, except my chosen solution is using Apple's Airport products. My Airport Extreme (wireless hub) serves my main desktop and creates a wireless network. When I get my hands on an Airport Express (wall plug unit thingy, it will be connected to the wireless network as a client and serving it's signal to another router (my old wireless one). I'm *hoping* I can get this to work.
