In the April/May 2001 issue of XML Magazine, there is an article about Peer-to-Peer Technologies and Ken Levy of XMLFund is one of the contributers.

For those who don't know Ken, he was a FoxPro "guru" and even worked at MSFT as a consultant. He created many tools for VFP like Super Class, BuilderB and programs to create XML data from VFP tables 2-3 years ago.
