You write '1 + 2' in a math formula and type 'M-x math-extern maple simplify' to get a '= 3' added. Alternately, you can mark the '1 + 2' and it will get replaced by '3'. In general, 'M-x math-extern foo' will call Maple's 'foo' function on the selected expressin. > I'm interested to add mathematica support but I'd like have more > information about what has been already done.

You basically have to add a function 'mathematicize' (or whatever) to every math inset (or at least to the ones you are interested in) and there you put code to transform the inset into Mma syntax. Usually you should be able to copy the 'maplize' function and replace parantheses by square brackets and things like that. Than you need to have a look add math_extern.C and formulabase.C and hook calls to these new functions in. You need to call Mma in some kind of command line mode that produces minimal output (either a result it LaTeX or an error message) and parse this output. Just look at what the maple and octave backends do. It's not exactly rocket science but quite a bit of work.
