You may be interested in what David Hoskin is doing for one of our
GSoC projects:
https://bitbucket.org/dhoskin/9webdraw
He's been producing weekly status updates, which you can follow
along with over on the plan9-gsoc google group:
http://groups.google.com/group/plan9-gsoc
It's not done, but he's gotten promising results and is still working on
it. Check it out.
It'd be interesting to see how simply something for Omero could be
done, bypassing draw entirely. I really like the model you came up
with there, and wish there was more diversity in implementations.
