Chemical Guys out in SoCal has a Eco Wash wash system which looks decent. I have no experience with it though. Looks interesting.
I attended a local meet at the Chemical Guys shop in Los Angeles and attended a DIY detail seminar there as well.
The waterless system would seem to fit your needs perfectly. The POD system is great if you want to spend some dough and/or want to start a business. However, you can purchsase the Eco Smart by the gallon and apply it with a regular hand spray bottle.
