Well, the inspiration for this proposal actually comes from OSX where
they have the built in screen dimming flicker functionality if you
enable it. I don't have access to OSX at the moment, so I can't say
where exactly you can enable it.
On the Windows side, there were some addons I could download to help
notify me when email came in. One particular app was imap-notify. In
addition to the sys tray application, it also provided a popup window in
the center of my screen which was very much a benefit to me with my
visual impairment (I have no peripheral vision.)
It is the OSX component that I wanted to not only emulate, but expand
upon with my suggestions for plugins.
I don't have access to Windows or OSX these days. However, you do
(judging from the email you sent, heh), so perhaps you could look around
and see what XP or Vista has these days and let us know?

Absolutely. We have to recognize that there are factors that exist.
Geographic locations where regions may not have more modern machines,
economic issues where unfortunately, people with disabilities tend to
have less buying power.
And then there's the technical problems. Compiz is a great solution but
it doesn't always work, even if you have the supported hardware. I want
something that is definitely agnostic and not dependent on having
additional components. And I want ease of use. So usability factors
come into consideration here as well.
So, I guess an additional question here is, should we be discussing the
"ideal look and feel" of such an app before it gets taken up by HFOSS?
Interns only have 3 months to work on this and it might behoove everyone
if we did a preliminary discussion of best look and feel so the interns
can dive in and get their hands dirty under the hood.
Or perhaps HFOSS would relish the opportunity to give the intern a "From
Conception to Implementation" project. I don't know.
One other thing. We will need technical mentors for this. I will
gladly and excitedly be the usability mentor, but I'm not qualified to
be a technical mentor. Volunteers please?

There is of course one drawback in that not all applications use the notification pop-up bubbles. How to work around this is another question to be dealt with.
