I am looking for a gadget that allows me to Capture HDMI from a PS3 and send it over the network. Preferably ethernet, but WIFI would be OK.

Something like this:
But waaay cheaper

If anyone is interested in details:
I have a PS3+360+OUYA+ATV2 in a closet, connected to a 2x4 MDMI matrix. Sometimes I would like to tinker with one of the consoles even when the TV is occupied. I would then have this gadget on one of the HDMI matrix outputs broadcast the video+audio over the network, so that I could use another device (laptop, iPad, etc) as a TV. Depending on the amount of lag introduced with this gadget, I could perhaps game, but the goal is to be able to tinker with the consoles even when the main TV is occupied.
