As for the number of programs you can have, I think you're having a conceptual issue. You can write one program that will handle multiple types of meat and/or timing cycles. the question is: How much program space (i.e memory) does any particular chip have ? THAT will limit the size of the program.
hmm.. I got it from somewhere else that you can only have one program on the chip at a time, but I have been reading code all morning trying to figure out out a bit and I might be able to have a selectible loop routeen, but having two seperate programs isn't a big deal either as it takes a couple seconds to upload the one you want to use. or if I use quick disconects for the inputs/outputs I could easily have two units and just plug in the one I want. I actualy found a PID front end here
http://www.arduino.cc/playground/Code/PIDLibrary so i need to do some more reading to figure out how to combine it with my other requirments.
