Best Route Between Multiple San Francisco Properties?

I thought some of you might be interested in this, my company just rolled out a new online program that will let you search for SF listings, and then will map the best route to take between the properties. If you are interested you can click here:  http://www.zephyrsf.com/user/register?key=YWdlbnQ9MzIxMzE. It will ask you to sign up with your name and email address, but as always nothing will be done with your information, and you can always unsubscribe. I gave some thought before offering this here because I try not to be salesy on this site, but I think it’s a pretty helpful program.
