Remark: NetFront is represented in this WG.

Regarding screen-reader behaviour:
I would await here more input from WAI people and screen-reader developers and users than from the browser vendors. And this should be in terms of "what" is required and not "how" it is to be realized.
My understanding is that a screen-reader operates on the DOM abstraction layer (structure/collections, but what about CSS?) and - indeed - this depends on the browser (the APIs are usually available). Here the role of the pure browser technology usually ends. 
"How" the above abstraction is presented to the user is usually "special-cased", I agree. It's up to the final implementation/integration whether e.g. collections are available within the UI.

>From the general point of view I assume there is a group of features required by both a screen-reader and a mobile browser that is usually operated by means of the 5/6-key-navigation. Focus management [1] is one of those and may need more attention.

At least Opera Mini, Safari, Opera Mobile, Pocket IE, S60 Browser.

Blazer and NetFront are not represented. I don;t know what other major  
phone browsers there are. <http://marketshare.hitslink.com/report.aspx?qpr

I don't know of any screen reader that doesn't special case the  
browser to some extent.
