Our builder had a sub-contractor install ceiling-mounted speakers in each
of 9 zones in our house. Each zone has a local impedance-balancing volume
various zones, and volume controls the zones .. all controllable from a web
browser or Android application.
-More details will be posted soon!
+## Artifacts ##

+The prototype hardware design current gEDA files are available from
+[git.gag.com](http://git.gag.com) in the project
+[hw/usbclassd](http://git.gag.com/?p=hw/usbclassd;a=summary).

+Bdale gave a [talk](http://youtu.be/gMTKyW6MXME) at Linux Conf Australia
+in January 2016, [slides here](http://gag.com/bdale/talks/2016/lca/audio.odp),
+which led to [an LWN article](http://lwn.net/Articles/674191/) by Jon Corbet.

+## Future Plans ##
+
+The initial design is working very well. We're pondering the possibility of
+making enough boards to sell, watch this space for more details!
