You need something really powerful, but at the same time ubiquitous. Remember a facet of the web is universal readership. There is no universal interptreted programming language. But there are some close tries. (lisp, sh). You also need something which can run in a very safe mode, to prevent virus attacks. Ideally, the language should include object-oriented inheritance, a basically functional nature, and a clean syntax. It should be interpretable and compilable. At least one public domain. A pre-compiled standard binary form would be cool too. It isn't here yet. In reality, what we would be able to offer you real soon now with document format negotiation is the ability to return a document in some language for execution, with the option of being able to provide it in several languages, the language being a "data format" which can be negotiated between client and server at run-time. For, for example, one could provide it in viola script and/or in /bin/sh which would cover most ofthe unix world. Tim BL
