So up to 255 satellite positions are supported by the SatIp protocol.

Does that work only for the four channel switches or also for the sixteen channel DiSEqC 1.1 switches? Pointers to documentation would be appreciated.

The MythTv SatIP Wiki states that only one channel (PID) is passed in a full mux stream, and therefore Multirec would not be possible. The protocol however states that multiple PIDs can be selected, and dynamic adding/deletion is supported (without affecting the other PID’s) This would allow Multirec, correct? Described on page 44 and 45 of the document.
