You should be able to connect any audio-video devices to it that use composite or component connections. You'll be able to stream off of it, I just don't believe you will be able to control the device it's connected to.
Do you have an old VCR in the attic ? Anything that has a coax input and an RCA (Composite) yellow output will work. And you will be able to control the device, I might just have to build a Custom Remote for you.
