A lot of my initial problems seem caused by the fact that live regions simply do not function at all with NVDA under Windows 2000, which is the OS I have in my VM. Switching to Windows XP allows at least some functionality for live regions - however some aspects of ARIA still seem broken, for example audible feedback for progress bars. We will most likely be looking at this issue wrt. the Uploader today. I am using the stable "2010.2" release of NVDA for testing.

In NVDA 2010.2b2, I didn't hear the telltale progress bar beeps on the Uploader's total progress bar. I think this may well be a regression in the Uploader.

Mike, can you do a side-by-side comparison between the version of Uploader in the AEGIS demo branch and trunk to see if we've got a bug? If it didn't work in the AEGIS demo branch, we should decide if this is required functionality for the release (I think it probably is) and implement it.

I presume this is a known issue with the reorderer.

It seems that the current crop of screen readers are only auto-switching on the application role. 

Would wrapping the Reorderer in role="application" resolve this issue?

Here's a suggestion: if someone has time this morning, let's apply Antranig's patch and do some early testing. If the fix looks promising, let's include it in the release. If we find any issues with it, let's punt for 1.4.
