A satellite alone is just a dumb amplifier. If you want to share bandwidth and access, you'll need a lot of ground equipments to operate the access-layer (e.g. relying on DVB-RCS). The project is not talking about the Telemetry Tracking and Control (TT&C) of the satellite. TerreStar-1 is a GEO satellite and you'll need to make regular manoeuvrings to keep the footprint stable too. Operating a satellite is costly and require a 24/7 staff... I don't really think that the project is realistic with such level of funding.
