I was trying to find an "HDMI condom" (equivalent to the usb ones [1]) but came up dry. Does such a thing exist yet, or is there just no market? Is it possible to use something such as an HDMI splitter to accomplish the same thing, or can those pass Ethernet as well, and how would you be able to tell?
