``[IBM] WebSphere Transcoding Publisher is a tool that is considered "protocol agnostic," meaning that this technology will soon allow any Web content to be easily ported on any "display" device.... Meantime, IBM is now keen on promoting "open standards" and "open source" computing as it declared that WebSphere will run on any platform, or that is at least 30 hardware platforms, and a list of computing environments such as Windows 2000, Linux, HP-UX, among others. "IBM is particular about not building a suite of Web applications but components that can be modular and can scale up," said Dutton.'' http://www.newsalert.com/bin/story?StoryId=CowVTqc4bmdaWnd I consider WebSphere, along with M$.NET, JavaSpaces, E-Speak, etc. to be similar enough to Piper to be considered "commercial competitors". A big difference seems to be the reliance of these systems on the web browser, perhaps a mistake. Also, looking at the bunch we have on this list, I'd say Piper will be a bit more tuned toward scientific and technical computing than e-commerce and personal productivity ;-) Cheers. Jeff
