My 2 cents.

I think the midishare output class in CM schedules output in
realtime.

But CM has powerful tools for generating (and analyzing) patterns
and control structure at various levels.  A good use of CM in
realtime situations is running pd or supercollider or some other
realtime sound-engine together with CM.  And calling various
processes in CM at will to generate .qlist-files or similar for
pd or files with lists of instrument-calls for supercollider.

Heres a io-class for outputting to a .qlist-file (intended for
PD's qlist-object) together with an example fm-object in case you
want to try it.  Just load it in after booting cm.

If you're in for a lisp-based realtime DSP tool to replace PD or
supercollider, take a look at Kjetil Matheussens new
rt-engine.scm for snd, available in the snd-7 distribution at
CCRMA.  The interface is all scheme, like clm and cm, and it
seems to run very efficiently.

This should be straight forward if you know of any such tool.
There used to be (is?) a vrml-output-class in cm.
