Hi Eric,
I've gone through your ob-maxima.el, and tried to re-work it to the
point where it can be included into Org-mode -- mainly just switching to
a couple of Babel "best practices", and replacing some shell script
munging with elisp munging.
Please try out the attached version (packaged as a patch against the
current Org-mode head) and let me know if it works --- i.e., If I
haven't broken it too badly. If it works I think we can fold it into
Org-mode immediately.
Cheers -- Eric

+
+;; Org-Babel support for evaluating maxima entries.
+;;
+;; This differs from most standard languages in that
+;;
+;; 1) there is no such thing as a "session" in maxima
+;;
+;; 2) we are generally only going to return output from maxima
+;;
+;; 3) we are adding the "cmdline" header argument
+;;
+;; 4) there are no variables
+
+;;; Code:
+(require 'ob)
+
+(defvar org-babel-default-header-args:maxima '())
+
+(defun org-babel-maxima-expand (body params)
+ "Expand a block of Maxima code according to its header arguments."
+ body)
+
+(defun org-babel-execute:maxima (body params)
+ "Execute a block of Maxima entries with org-babel. This function is
+called by `org-babel-execute-src-block'."
