That is good news.

Basically, when I say a11y support is needed in gtkmozedit, I am mainly
referring to the following:
- The atk relation must be established between all the widgets (toolbar,
menubar, any other widget) so that gnopernicus, speech reader, etc. can
use them.
- The main text editing widget should have an atk interface. i.e. so the
typed typed is continuously readable by speech reader.

For further information, you might want to get in touch with Nagappan
( anagappan novell com ), who works in a11y based LDTP project. A
mailing list useful for this type of development is:
http://mail.freestandards.org/mailman/listinfo/accessibility-atspi
I believe few IBM and Sun guys are already working in mozilla a11y
project so they could give some valuable inputs too, in making
gtkmozedit a11y enabled. A peek into epiphany browser, which is a11y
enabled, and is based on gtkmozembed, might be helpful too.

I have not described the a11y requirements for rendering part of
gtkhtml, since we are focusing on editing for now.

Actually, gtkhtml does all the above locally and does not use any
plugins, or standalone utils, so I am not sure of some alternative.

Mainly gif animation is needed. Flash isn't supported by gtkhtml.

Please feel free to mail me or catch me on irc (nick: ksh) for any other
inputs I could provide.
