GroupDAV: Standardizing Groupware

IGnatius T Foobar writes "There are lots of open source groupware products out there, but the perpetual problem has always been that we don't have a single, unified standard protocol to connect open source groupware clients to open source groupware servers. GroupDAV changes all that. Support for GroupDAV now exists in Citadel, OpenGroupware.org, KDE Kontact, and connectors are currently in beta for Evolution and Mozilla Sunbird. Unlike CAP and CalDAV, the GroupDAV effort is backed by real code that works today. "
