I am not an expert on this. I did a project for an interactive TV grant a few years ago. We did everything in VRML. It was a nightmare because the user had to have the plugin and it was difficult to get them to stop and take the time to download it. With Flash, and the ability to load and unload movies so quickly, I think that is more viable. As I say, I am no expert in this but I do have a real interest in it. Keep me posted as to your findings. I believe it is the furure of the web. cheerio lululee
