Need advice about a networking product

My unabashedly geeky goal is to run two Xboxes on Xbox Live with minimal cables.

I know you can get plug-in cards that add wireless capability to an Xbox, but I don't want something that specialized. I want a different sort of product, which I imagine *must* exist; I'm just having trouble identifying what it is called and where I can buy it. Maybe someone can point me in the right direction.

I already have a Netgear wireless router/gateway. I want a device that communicates with the Netgear, and which has at least two standard ethernet jacks. I would put the device in the room with the Xboxes and connect both to it with very short lengths of cable. They would then communicate with the Netgear through that device. I think this would be much better than running cable all the way from the Netgear to the room with the Xboxes, and probably cheaper than getting each Xbox a separate wireless adapter.

If I'm not mistaken, Apple's Airport Express would do the job for *one* Xbox, because it has an ethernet port. I want something that can handle more than one device.

Thanks in advance if anyone can point me toward a particular product, or class of products.
