Yes, that's the way I did it.

Like I said, I think many local variables should be copied all over
the place by Gnus.

Err, hm.  I don't know anything about the implementation of
gnus-newsgroup-name, but I'll go look.

After typing `G c' in the Group buffer, it is possible to set local
variables in addition to group parameters.  I'm not sure what happens
when one does that, though.

???  I think I'll go read the sources, first.  I can't make heads nor
tails of what you're saying :-)  Not your fault, of course.
