 We're designing a completely open hardware and open source solution for
 whole-house audio distribution.
 
-Details will be posted soon.
+The key hardware component is a board containing a USB audio interface
+and stereo 50 watt class-D audio amplifier.  A set of these boards, one per
+"zone", get wired to speakers in the various rooms.  A Linux system runs
+software that controls audio stream sources, maps them to the various zones, 
+and volume controls the zones .. all controllable from a web browser or 
+Android application.
+
+More details will be posted soon!
