For those who are interested, I’ve put together the collection of links that I found on getting MathML to render in browsers on LiveWorks! I’m a little unsure about the status of Safari and Opera so if anyone familiar with MathML in those browser could provide any info that would be greatly appreciated.

Also, as a bonus tip that I’ve picked up while researching XHTML modes in browsers, if you save a file with a .xhtml extension (or .xhtm or even .xht I think) browsers will actually use their XML parser to read and render the file. Much simpler than reconfiguring your web server to send the right mime type if you’re just testing stuff. Web servers with up to date extension to mime type mappings will also serve the file as application/xhtml+xml which is handy if you are serving static files too.
