Thanks for sharing this, but I'd prefer something with a first-class lisp interface, and from what I've seen Maxima's is not that great. I just starting taking a look at some alternatives and it seems like in addition to some wrappers around Maxima, there are three others:
https://github.com/OdonataResearchLLC/weyl
http://www.mitchr.me/SS/mjrcalc/
http://fricas.sourceforge.net/
Of these Weyl which is a fork of Cornell's SimLab interests me most. I'm actually in midterms currently so I'll have to wait a second to do more in depth research, but it seems like there is a great selection, even if in Common Lisp and not Scheme.
