I saw in the magazine Popu

I saw in the magazine Popular Science, a wireless network booster. I forget what it’s called, but it was only $50 and with many of them, it is possible to extend a network as large as necessary.
The largest question would be streaming the video.

Looking at some of the video switchers out there, Focus Enhancement’s MX-4 series have an ethernet port. What can you do with it? Does anyone have any experience with video switchers like that?
Or is there a program on a computer than can stream video to computer, live?

Thanks a lot for your comments
