-** litorgy-R
-*** TODO ability to select which of multiple R sessions is being used
+   The other languages (aside from emacs lisp) are run through the
+   shell, so if we find a shell solution it should work for them as
+   well.
+   
+   Adding an ampersand seems to be a supported way to run commands in
+   the background (see [[http://www.emacswiki.org/emacs/ExecuteExternalCommand#toc4][external-commands]]).  Although a more extensible
+   solution may involve the use of the [[elisp:(progn (describe-function 'call-process-region) nil)][call-process-region]] function.

+   Going to try this out in a new file [[file:litorgy/litorgy-proc.el][litorgy-proc.el]].  This should
+   contain functions for asynchronously running generic shell commands
+   in the background, and then returning their input.
+
+*** partial update of org-mode buffer
+   The sleekest solution to this may be using a comint buffer, and
+   then defining a filter function which would incrementally interpret
+   the results as they are returned, including insertion into the
+   org-mode buffer.  This may actually cause more problems than it is
+   worth, what with the complexities of identifying the types of
+   incrementally returned results, and the need for maintenance of a
+   process marker in the org buffer.

+** TODO ability to select which of multiple R sessions is being used

+    Maybe this could be packaged into a header argument, something
+    like =:R_session= which could accept either the name of the
+    session to use, or the string =prompt=, in which case we could use
+    the =ess-switch-process= command to select a new process.
