There has been some discussion lately of pretty front ends to maxima.
Although I fall in the Emacs camp for my own use, it occured to me
that what could be very useful would be the ability to generate
interactive web pages. One system that can do this is Cinderalla
(www.cinderella.de). Cinderella works be generating a java applet
containing the run time.
I guess the simplest option would be to generate math-ml pages with
cgi-scripts back to some brave host willing to run maxima code.
On the other hand, since there exist a lisp systems (well, the
ones I found are scheme. I'm too ignorant to know if that is
fatal) that target java, a more ambitious project may be
possible.
