Things You Can Do with a TV-Elite IR Kit?

man_ls asks: "I have a TVElite kit that no longer works. It was used for displaying my computer monitor on both a TV and computer at the same time. It came with an infared attachment to allow you to use the remote to control the volume on both devices at the same time, that seems to be made by EMC. Inside is an IR connector, an EMC IC, a serial connector, and an infared receiver I think. Does anyone have any more information about some 'fun' things I could do with this? (such as an IrDA for my desktop computer)"
