Eric -- Thanks, very cool.  I'm toying around with this approach to do dynamic
code-block evaluation in the Org-mode clone I'm making in Vim. No problem with
on-export-evaluation, since the vim-org-clone just saves the file and issues a
batch mode org-export or org-publish command to emacs, which takes over from
there.

I think this dynamic evaluation could be useful, but it also seems like a new
server is getting called for each emacs --batch mode call.  That's cumbersome
for this dynamic-evaluation stuff because of start-up overhead for emacs on 
each call.  Is that the way its supposed to work?  

I'm working on Windows7 and have an Emacs client running when I issue the 
batch command, which I assumed also means there is a running emacs server.  
Is the
call getting made to the running emacs server?  If so, is there some way to
avoid the startup overhead (which seems to come from 'Adding c:/program files
(x86)/emacs/EmacsW32/lisp/ to load path.').  Or, if my batch call is _not_
making use of the running Emacs server is there some way to get it to use that
server?

Thanks again,

Herb
