Hello Kirk and others who are interested, There are some who highly promote LaTeX for writing and reading technical documents. I certainly say for those serious on using technical notation and will make plenty of use then learning LaTeX can be a good investment, however I would never promote it for reading (it really is a document preparation tool) and also for many who may only encounter technical notation from time to time it really isn't worth the investment (if learning it for the technical notation is the only reason, I know some like using it for about everything in which case you will be making great use of it). Another mark up system, I think meant to be easier to learn but I am unsure whether so powerful is the asciimath notation (sorry I don't have a link to hand but I am sure a quick search will find relevant stuff). Asciimath is mainly used on the web but is therefore suitable for all platforms. Other more specialised systems exist like triangle and lambda, but I think these may be a bit limited and the editors which were designed for them were only developed for windows (not good for people here as its a linux list). A new system which John Gardner of ViewPlus is creating, and which I have been involved with when he was thinking of it is called Linear Editing and Authoring Notation (LEAN). A preprint of a paper by John Gardner on the LEAN system can be found at http://www.access2science.com/jagqn/More%20Accessible%20Math%20preprint.htm and I personally feel the system is a good way forward. LEAN is unicode based so should be simple enough for applications to work with. While at the moment work has mainly been focussed on Windows screen readers, I could imagine it working fine with others like Orca if someone made a suitable symbol dictionary. I have been working on a greasemonkey userscript so that one could read MathML equations in firefox using the LEAN system, that userscript can be found at http://bitbucket.org/mwhapples/mathmlreader but I must worn people its still work in progress. Finally there are other useful documents on the access2science.com website. Hope some of this has been useful.
