Aren't we forced to do so, right now?  As in the following home-made example:

#+TITLE:     Show differences between files

* Code

Assuming you have two directories (namely =xhtml-dir= and =xhtml-dir-bak=,
accessible from this local directory), the following blocks of code will
compare named files (see column 2 of table) in them, in both /text/ and
/binary/ versions.

#+srcname: diff-text
#+begin_src sh :var file=""
diff -sq --strip-trailing-cr xhtml-dir/$file xhtml-dir-bak/$file > /dev/null
case "$?" in
  0) echo "identical";;
  1) echo "differ";;
  2) echo "no such file";;
  *) echo "?";;
esac
#+end_src

#+srcname: diff-binary
#+begin_src sh :var file=""
diff -sq xhtml-dir/$file xhtml-dir-bak/$file > /dev/null
case "$?" in
  0) echo "identical";;
  1) echo "differ";;
  2) echo "no such file";;
  *) echo "?";;
esac
#+end_src

* Results

| FPH | File                          | Text      | Binary    |
|-----+-------------------------------+-----------+-----------|
| M   | "Icopreations.xhtml"          | identical | identical |
| M   | "Ocuevaonspfiessai.xhtml"     | identical | differ    |
| M   | "Ocuevain-tut.xhtml"          | differ    | differ    |
| M   | "Ocuevatagessai.xhtml"        | identical | differ    |
| M   | "Ocuf2-stg.xhtml"             | differ    | differ    |
| M   | "Ocurolro.xhtml"              | identical | differ    |
| M   | "Ocuroliers.xhtml"            | differ    | differ    |
| M   | "Ocurolredit.xhtml"           | identical | differ    |
| M   | "Ocusigletiquebc1233de.xhtml" | differ    | differ    |
| M   | "Rocsaieprestations.xhtml"    | identical | identical |
#+TBLFM: $3='(sbe diff-text (file $2))::$4='(sbe diff-binary (file $2))

I had to enclose the filenames between double quotes, for the =sbe= code to
work.

Trying what you wrote on
http://eschulte.github.com/babel-dev/DONE-literal-values-from-tables.html,
that is using $$2 instead of $2 has the following behavior: when evaluating
the table, Org prompts me for a "Lisp expression"!?

Best regards,
  Seb
