Overview of desired features

Reformed Churches Locator is a web application that provides a filterable map and directory of all reformed churches in the world, broken down into denominational and other groupings. It aggregates churches' contact info via RSS feeds from various sources, and provides a widget that can be integrated into a website using a simple code snippet. It also allows administrators & the public to edit church contact info. The intended result is that Reformed Churches Locator will unite and then supercede all current online Reformed church directories, and provide both church members and administrators more unified and up-to-date access to this information.

Consider these sites' ideas as a starting point:

http://www.reformiert-online.net/weltweit/index.php?lg=eng - data
http://mountainretreatorg.net/churchit/churchit.html - data
http://www.marshillchurch.org/locations_and_services - nice design

Reformed Churches Locator is intended to improve on the ideas implemented in PresbyterySite.
