C|Net has an interesting interview with David Temkin, the CTO of Lazlo Systems. Lazlo produces a now-open-source product for easily creating rich Internet applications, similar to Macromedia's Flex Presentation Server. Lazlo and Flex each use their own XML-based languages to allow developers to create rich web based Internet applications that run in Macromedia's Flash player, without requiring the use of the standard Flash designer-oriented authoring tools.
