My company has created a zipcode-radius search for Mosets Tree and Hot Property (ex: search for listings within 25, 50, or 100 miles of zip code 30022). We are porting it to community builder for my wife's social site. It is currently a single shot installation and has to be installed by hand. On the upside we do have public domain postal code databases for the U.S., Canada, Mexico and some European countries.
I am posting this to gauge the interest in the CB community in this component. If there is enough we will convert it to a full advanced search component so anyone running CB could install it easily.
Basically without having to make members' zipcodes public, a user could search for members within x miles of a zipcode they enter.
If you are interested, drop me a note or post here with any ideas/suggestions you have. If we do it we will need beta testers.
