[Twisted-web] generating Canvas.swf without needing Flash

[rpiwork at notebookmargins.com]

Hi Folks,

Questionmark?

I just subscribed to this list because twisted seems like such a
fascinating thing and was surprised by this post. Is the twisted web
community interested in swf? I confess to have thought that there would be
prejudice against it's use in the twisted community. Was this a prejudice
of my own? Ironic. Has swf truely become that accepted? I hadn't imagined
it would be.

Followup questionmarks, and more to the point.

What is canvas.swf for? What would your desires be along these lines?

Thanks,

-Cort
