ODOT does GLONASS, but only in a "virtual" ntrip that gpsd does not
understand and no one can show me what messages are required.

Just a follow-up information point:

I got a login to the Ohio DOT virtual reference station network, which uses the Trimble VRS system. It appears the only unique requirement is that the rover needs to send an NMEA GGA sentence to provide an estimated location used to construct the virtual reference station location. Other than that, the traffic flow is all outbound from the network to the rover. (I don't know if it needs just a single GGA sentence at login, or at some interval.)
