This is kind of true, but it is not hacking the lisp read table. It just
reads
characters from the user's input.
How can I just sandwich lisp in maxima like "1+f(10) +
> lisp((+ 1 2 (the :three) 4)) + 2"? (where "lisp" is a maxima macro and

You could do this: LISP("(+ 1 2 (the :three) 4)") +2 without too much
trouble. Then you could have the LISP function do something like
(defun $LISP(x)(read-from-string x))
However, the internal maxima form for (+ x y) is likely to look more
like ((mplus simp) $y $x), if you want to mix them together.

At the moment it seems that the commercial Macsyma is unsupported and almost
unavailable. Good luck contacting the current owner.
You can get a copy of DOE Macsyma that is essentially unrestricted,
and use that, if you want to sell what you've done. If you don't want to
sell what
you've done, GPL, LGPL, etc. doesn't matter much.
