If you get the progress beeps working I would be more than willing to help with testing. Just send the code and instructions on how to add it. I have wanted progress bar beeps every sense I started using Orca in 2007. It will be absolutely awesome to finally get my wish. Also, just let me know if there's anything I can do to help.

Whether or not it winds up being far too ambitious to start with is
something I'm not sure of. The problem you'll run up against currently
is lack of Gecko support for it.
You may be aware of this Orca RFE:
("[blocked] Orca should provide access to MathML content in Firefox")
The Mozilla bug which is blocking us is here:
(MathML objects exposed as "dead" accessibles via at-spi)
It's a couple of years old now. Since you have an interest in seeing
this implemented, perhaps it would be of use to ping the Mozilla guys on
the Mozilla bug and start a dialog about how to implement a solution
which, in turn, would make it possible for us to handle it within Orca.

As I recall, Rui Batista has done some work in this area. I'm hoping
he'll chime in.

In terms of making things bite sized, it might be worth tackling them as
1. Implement sound for progress bars (we won't actually check that in
without a setting, but it doesn't *need* to have a setting for you to
get this feature working.)
2. Add a setting.
The way we do settings within Orca at the moment is less than ideal, and
largely the result of the Orca team's lacking profound insight (and/or
psychic ability) in the early days into what all we'd need to implement
settings-wize to meet user requirements. So it got built up as we went.
A while back, I started looking at moving everything to gconf. But gconf
is being deprecated by the GNOME community. So had we gone that route,
we'd be forced to make (another) switch/move in our settings. Because we
didn't, the broader community simply frowns at us for rolling our own
settings handling. <grin> My intent is to address this after the GNOME
community completes the gconf deprecation.
I will add the writing of documentation related to how to add a new
setting within Orca to my to-do list. In the meantime, here is an
example commit that Attila did to add the option to have Orca speak the
position of an object (e.g. within a list or group):
HTH. Take care.
