Yes, I've started working on a gnome/gtk based newsreader. At the moment
only some very basic functions are working (downloading newsgroup list,
article list, htmlifying and showing articles). And only the NNTP protocol
is supported. I intend to check the work into the CVS tree when I reach
basic usability, maybe in a few days.

with a good architecture this is very easy to implement. But OTOH I think
the mail reader is to read mail, not the news reader. What's the point in
extending a news reader to able to read news? Isn't that what's CORBA for?

I will try my best :)

that is partly implemented

this needs working

mime decoding needs work, the rest is functional :)
