htmlb Browser Support

Has anyone tested the different htmlb tags on browsers not officially supported by SAP/BSPs? We need to support more browsers than SAP and have done some preliminary testing of some simple components (textView, inputField, and button) on Netscape (even on a Mac) and Mozilla to see if we can use these components on the different browsers. If anyone else has done similar type testing, it would be nice to compare notes/share the results. We would like to end up with a spreadsheet listing the htmlb components and which browsers seem to handle them successfully.

Note that even to test on unsupported browsers, we had to define our own zzcontent to keep the SAP-standard content from erroring out due to browser-type.
