Even if this PSK/FM design was only in LEO it would be very heavily used. I believe but I think there would be limitations to the volume of traffic that it would get at a higher orbit.
The PSK satellite was part of the presentations during the 2014 AMSAT Symposium in Baltimore.
Page 13 of the proceedings begins an article on a 1.5U cubesat from the US Naval Academy called BRICSat-P. This 1.5U half of a 3U cubesat carries an electric thrust experiment.
The remaining 1.5U of this 3U package contains PSAT. It is a 10 meter SSB uplink using PSK-31 with a downlink on 145.825 MHZ FM. (See page 19 of the 2014 proceedings for a paper on PSAT by Bob Bruninga, WB4APR and Dr. Mirek Kasal, OK2AQK).

The disadvantage of the L/S in the higher orbit is it will take away the advantage I mentioned about a ready pool of HF PSK operators to immediately use the thing. That would put it back into the realm of a niche hobby for the few.

Add to the aforementioned - all in a sat that is in a Molniya type orbit with L & S band capability like AO-40 (sobsob)
