If you are interested in it, you can try the latest Gnus CVS and
the following patch:

ftp://ftp.jpl.org/pub/tmp/nnrss-patch-20041214.gz
or http://www.jpl.org/ftp/pub/tmp/nnrss-patch-20041214.gz

It is still under development and we need to verify it further.
Non-ASCII group names aren't supported yet with the `j' group
command etc.  I made the following function for the replacement
of `completing-read'.  However, it is rather slow.
