Well they do output a bit more power some 25 or so milliwatts. I've used
them to carry SPDIF over short distances such as the original poster
requires and much longer with bigger antennas..

I know this can be done and I've been looking into it for a while with
the interest in using it for subwoofers and/or rear/surround speakers
in a multichannel sound system. This would eliminate the need to run
many cables around or under the floor.

One OEM I spoke with (and whose devices seem suitable) said that
receivers could easily and cheaply be included in self-powered
speakers. Unfortunately, all the 'high-end' speaker manufacturers
evinced curiousity but no real interest.
