Notes on XmlHttpRequest
SitePoint's PHP Blog: Dynamically Typed reports on JpSpan, a facinating project that I previously blogged, albeit with a different name, that was trying to build tools in PHP and Javascript that could fetch data from PHP into a web page which has already loaded, without reloading the entire page. The new project, named JpSpan, has a wiki to report on its progress. FWIW, XmlHttpRequest is part of the Web Applications 1.0 Working Draft.
