I would very much support you continuing development on Orbited.
In fact, I believe I can help, or already have patches for most of the
above issues you mention.  A lot of this is result of my "Hotdot" project,
"Create realtime webapps using Django + Orbited + Twisted":
http://github.com/clemesha/hotdot

Specifically, see here for Orbited and twistd working together:
http://github.com/clemesha/hotdot/blob/master/server.py

and see the below for patches that improve handling lost connections gracefully:
http://gist.github.com/256582

Finally, it would be awesome if you put up your improvements on Github
(just a suggestion :-),
then I can easily fork and starting adding improvements, and you can
pull and we can move this forward.

p.s. I haven't found many issues with the frontend JavaScript code, but if you
have specific issues that you could point out, I'd love to try to help.
