Ok lets just start off with the most common question;
What is CPPM and SBUS?
Answer: Both CPPM and SBUS are special outputs from a receiver that carry all 8 (or more) channels on a single servo connector. You can output 16 channels on a single connection using SBUS, and 8 channels using CPPM. This is great for flight controllers in multi-rotor aircraft as we no longer need to have a bunch of wires to connect each channel. Now this is also great for aircraft as we can clean up the wire mess in our planes, and do some unique installs.
No one has made an affordable SBUS servo until now, and I'm not sure anyone has made a CPPM servo, and I doubt anyone has made a single servo that can work with all three formats. The D25SA and D25MA from FrSky not only work with SBUS and CPPM, but they can connect to a normal pulse width modulation (PWM) normal servo output. This makes your investment in servos much easier.
Many modern receivers now offer CPPM or SBUS ports built right into them, you can simply plug these servos into that port and the servo will respond to whatever channel you tell it to respond to. Need to add another servo to your plane? Just use a "Y" splitter extension and ad another. No expensive hubs are needed. You will need a channel changer to set the servo to the desired channel, once set, that servo will respond to only that channel.
NOTE: CPPM mode is not currently an option as a new channel changer from FrSky will be required for this feature.
