Hi.  Patch seems to work.  Tested on fresh emacs-snapshot (24.3.50.1)
install on ubuntu with org-mode freshly pulled from git (7.9.2).

#+NAME: hobbits
| bilbo | frodo |

#+name: execOnExample.com
#+BEGIN_SRC sh :var foo=hobbits  :dir /gmj@example.com: :results output
hostname

echo executed on `hostname` at `date`

echo two $foo

#+END_SRC

Similar procedure on a mac still yeilds:

FYI/Thanks,

`/scpc:gmj@example.com:/var/folders/j6/j6w17khs3vl9s2_yg4rb5zsm0000gn/T/input-61683xyS',
decode using `mimencode -u -b >%s' f\
ailed
