There is GNU TeXmacs, an interactive typesetting system which can work
as a user interface for a number of CAS and plotting softwares. The
plugins included in the distribution are:

  axiom, gnuplot, gtybalt, maple, maxima, pari, r, scilab, giac,
  graphviz, macaulay2, mathemagix, mupad, octave, qcl, reduce, yacas.

I have also heard that Matlab people are developping a texmacs plugin
of their own.

TeXmacs is a GNU project and licensed under the GPL.

It is not yet possible to "make computations over the internet" (the
CAS has to be installed on the same machine as TeXmacs) but TeXmacs
can be used as a web browser. The HTML conversion abilities are being
improved and there is already a sketchy support for MathML
presentation. In case you want more math, you can use just browse on
native texmacs documents over HTTP.

The UNIX version is pretty mature and there is a contributed
experimental Windows port.

TeXmacs is NOT a LaTeX front-end and is unrelated to emacs.
