Fruux, a cross between social networking and .Mac's sync service, is currently in beta testing and looking for people to help test the service. Fruux synchronizes address book, bookmark, and calendar files with each computer someone owns, and also gives the user the ability to synchronize contact information with others. This allows users to stay in contact with friends, business partners, and family, even if the contact information changes.

Users can beta test the Fruux application by applying through the main site, while a web client is due to follow soon.
