Hi Michael,

I am in a similar situation,

I think that's the problem.  Have you used evas bevore?  Evas is the
canvas used in Enlightenment.  There are two sets of python bindings
available, one from Enlightenment
http://web.enlightenment.org/viewvc/e17/proto/python-efl/ and one from
Kaa  http://freevo.sourceforge.net/cgi-bin/freevo-2.0/Kaa .

I have experience with Kaa (being part of Freevo) and technically you
should be able to render an evas canvas onto a GTK drawing area...
however, I ran into a problem / bug and it's not working here.

I haven't had a whole lot of time but I would like to play a bit more
with python-efl to see if I can do the same.  BTW you can see the demos
here:  http://blog.gustavobarbieri.com.br/

Please, let me know if you have further success!
