Wow this is really fascinating. Probably just in the amateur radio world though, right?
I imagine there are other satellite constellations that have used individual satellites to communicate with others in the network to expand content distribution in the commercial/military markets.

Perry Klein (W3PK) and Ray Soifer (W2RS) are believed to be the first two terrestrial stations to communicate using a direct satellite-to-satellite relay in ANY radio service. This was accomplished with A-O-6 and A-O-7. See P. Klein and R. Soifer, "Intersatellite Communication Using the AMSAT-OSCAR 6 and AMSAT-OSCAR 7 Radio Amateur Satellites, *Proceedings of the IEEE Letters*, Oct 1975, pp 1526-1527.
