Thanks for the catch, I'm now mentioning asy-mode in the requirements of
org-babel-asymptote.el, and asy-mode is now listed as the major-mode for
asymptote blocks in the `org-src-lang-modes' variable.  After grabbing
the latest Org-mode you should be able to edit asymptote source-code
blocks using C-c '

I don't believe that anything like this currently exists, but I agree
that it would be generally useful.  In the current setup the best way to
preview your work would probably be to...
1) jump out of edit-src-mode C-c '
2) re-run the source-code block from the Org-mode buffer C-c C-c

Some better options which come to mind are...
- use either a header argument or a language specific setting to specify
  that Org-edit-src should associate the src buffer with a temporary file
- add a command to org-edit-src-mode which writes the buffer to a
  temporary file
- something else...

Dan has more experience than myself in dealing with Org-edit-src so he
may have better ideas.  I do think this is an issue that deserves
further thought/discussion.

Thanks -- Eric
