not sure what you mean by "integrate" here.
if you mean to have a latex-typeset formula appear in the user interface,
i believe some user interfaces already do that.
follow the link below for a list.
> Are there better solutions than texvc?
you might take a look at http://maxima.sf.net/relatedprojects.shtml --
i'm guessing that each project listed there has come up with some
kind of solution, maybe something works for you too.
sorry i can't be more helpful -- let us know what you come up with.
