I had a look at the org-mode sources and found that this was quite trivial
to implement on the source level. E.g. the following patch embeds the
output of an org formula in ~~ to make it org-verbatim. This is easily
changed to another couple of characters that may then be set in
org-emphasis-alist to whatever formatting I fancy.
