Mike,
The cruise control is software. Remember, the car is already drive-by-wire and has no mechanical linkage between accelerator pedal and throttle. The 2001 car already has all the wiring and software for cruise control. The only things missing are the control stalk on the steering wheel and a two-pole brake pedal switch so the cruise control knows when you touch the brake.
I installed my own Toyota cruise control soon after the price became reasonable. So have many others. This is well documented on the Yahoo! groups. It takes 1 to 2 hours if you go really slow with breaks. I could do it again now in about 30 minutes. Since you know yourself I would not suggest you change your mind, but don't let anyone tell you this is difficult or time consuming!
I attach a report I wrote after my installation.
