You can find Shinzen's retreat calendar at www.shinzen.org and learn about his home practice program (monthly two- and four-hour phone retreats) at www.basicmindfulness.com. I've got several posts related to his work on my blog http://ow.ly/1ov3Q where you can also find links to YouTube videos and mp3s of his talks.

I'd be happy to try to answer any questions. You can reach me at daronlarson at yahoo dot com.
