Our friends in La Casa Roja are in the process, or about to be, of putting drip on all of their plantings. Check them out through the link on this site.
We are extensively landscaped on our quarter acre here, but are not automated because we regularly change things and have a lot in the ground, and try to be very water aware. We grow loads of really great things and enjoy doing the watering once a week, allowing our guy to water once a week also.
Also check in with Hotel Arco Aris on this site for more ideas. They even have a system to use their rain water
