Just so you know, all of the modules currently available for the RKL and the RKE will be compatible with the new Archon system. The RKL and RKE head units will act as remote displays. With the NET module you can change the status of channels and you can monitor, but you can not reprogram channel settings. The Archon system will be programmable via a web interface and you should be able to do whatever you want on it from wherever you are. Personally I think it is silly to be reprogramming channels while you are not in front of your tank, but thats just my opinion. I would never do that when I can't see and verify that the system is working exactly the way I want it to.
