This does look interesting. One possible problem I see is that I tried
a similar thing with TinyMCE and ran into problems on Safari. It seemed
that Safari doesn't automatically evaluate <script> tags when they are
inserted into the DOM, like Firefox does, so I had to change the
client-side javascript to specifically execute them. The changes are in
safari-fix.patch at http://trac.sagemath.org/sage_trac/ticket/4705.
I can't test the above in Safari, so I'm not sure that the above code
will run into this problem, though.
Thanks,
Jason
