Jamcast is a DLNA streaming media server. We've introduced a new API that will enable developers to make new digital content available for browsing and playback across the network to connected devices.
We're also building our own Jamcast plugins and are sharing the source code here on CodePlex with the hope that they will encourage others to join in and build some really cool plugins too.
