Hi Sam, You probably already know this, but there is some good historical information about PureData on www.PureData.info also there was a "future of computer music languages panel discussion" in an issue of computer music journal (maybe last summer) that I found very insightful. You could also look at Miller Pucket's websight, and I would mention last automns First International Pure Data Convention. As a foot note you could also mention planet ccrma at stanford low latency pure data kernal, and no doubt many other interesting branchs of the PD family
