BeamBoy PC to TV

Good morning troops! Is anyone familiar with a device called "BeamBoy"? Here is the link: http://www.beamboy.tv/bke189/index.php?s=120 I like this because I can rent it for a low monthly fee, and I have read the contract which looks very straightforward and fair. However, I want to make sure the technology is sound, so I thought I'd put it up here and let y'all vett it. Money is tight right now, and I have shut off the cable, but I do use Netflix a LOT, and it would be cool if I could beam it to the TV and we could all watch it. Also, it seems to me that my kid could be on the computer in the other room doing his thing and I could be watching my Netflix in the adjoining room from that computer and we would no longer have to have screaming territorial battles ending with great injury and destruction. And that would be good...:clap
