Microsoft Silverlight
Ever since before WPF had WPF/E we were hearing rumors about this product. Microsoft describes the product as "a cross-browser, cross-platform plug-in for delivering the next generation of media experiences and rich interactive applications (RIAs) for the Web. Silverlight integrates with existing Web applications. Silverlight media capabilities include fast, cost-effective delivery of high-quality audio and video to all major browsers including Firefox, Safari and Internet Explorer running on the Mac or on Windows. By using Expression Studio and Visual Studio, designers and developers can collaborate more effectively using the skills they have today to light up the Web of tomorrow." (http://msdn2.microsoft.com/en-us/asp.net/bb187358.aspx). I have seen some demos and I would describe it as some REAL competition for Flash.
Besides the fact that this product is going to turn web development on its head, I have it on good authority that it was actually named after David Silverlight a Florida .NET developer and the founder of such legendary websites as http://www.community-credit.com, http://www.nonprofitways.com, http://www.dwightbobbleheads.com, http://www.realtechnologyheros.com, http://www.xmlpitstop.com (well just about every webpage on the internet). I cannot reveal my sources, you understand NDA’s and the like, but I just wanted to congratulate David and wish him all the luck with his new product. Now if he would only give me a cut of the profits. . . .
