Dear Stewart, You can find some code using the Oz compiler from within Emacs Lisp as part of the Emacs org mode sources online at http://orgmode.org/w/?p=org-mode.git;a=blob_plain;f=contrib/scripts/StartOzServer.oz;hb=HEAD or in the source tree at contrib/scripts/StartOzServer.oz. I did some documenting comments, but if you have any questions about this just ask. (Note that there is some subtle bug, see last paragraph of http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-oz.html. However, this bug is likely on the Emacs Lisp side).
The other approach I mentioned is as follows. You define a data structure (I used a dictionary) that links atoms (symbols) to procedures. Whenever a message is received (I used a socket for communicating), then the matching procedure is called. This approach can be generalised with argument support as follows. You send stings representing nested data (e.g., strings with Oz records), parse these (e.g., with the parser generator Gump, http://www.mozart-oz.org/documentation/gump/index.html), then use the record label to access the procedure associated with that label from the mentioned data structure and call it with the parsed record. I implemented this approach in the OSC (Open Sound Control) interface of my software Strasheela (sending and parsing OSC messages). See online at http://strasheela.svn.sourceforge.net/viewvc/strasheela/trunk/strasheela/contributions/anders/OSC/?pathrev=2312 or in the source tree at strasheela/contributions/anders/OSC/). Unfortunately, on recent Macs Gumps seems to be broken. Quite possibly, the error is another case of the 64bit platform issue, as I never had such problem before trying to compile it on my latest Macbook with MacOS 10.6. When you try to compile Gump code (e.g. the mentioned OSC interface of Strasheela, but I tried it with other Gump code as well) on such a machine it results in an error like the one I posted after this message. I should really file a bug report for this problem. I probably should not release any new Strasheela version (even though I already finished a lot of changes) before Gump is working again. Unfortunately I cannot fix that myself, because I am not "speaking" C++ :-/ Should I file bug reports to the list of issues at the Mozart github (https://github.com/mozart/mozart/issues?sort=created&direction=desc&state=closed) or is there a better place I did not find. Thanks!
