Dan,
We are of the same mind. Ease of consisting was the main reason I chose RP. It works as advertised. Couldn't be simpler. The secondary reason for me was getting the control signals off the rails. Consider all the electrical noise, particulate filth, surface oxidation, intermittent electrical contact from rolling wheels and sliding wipers, and varying inductance, resistance, and capacitance of train track. The rails make a very poor pipe through which to send digital signals. This is evidenced by all the chatter one hears about blown decoders, lost addressing, unresponsive decoders, lost CVs and the like. The DCC manufactures should be applauded for making DCC work as well as it does on such a lousy bus system. RP radio communication seems a vastly better way to go about it and it is bearing out that way for me.
The only two drawbacks that may be of concern are: 1) Your friends' DCC equipment won't work on your RP layout; 2) You are restricted to Ring electrical components unless you build your own (circuit breakers, occupancy detectors, accessory controllers, etc.).
