Hi Stefan,

please come up with a real world use case for a mailing list
as user on a roundup nosy list.  

IMHO the nosy list is a very fine mailing list manager by itself, 
which is far more powerful than any other mailing list manager from
the users point of view.

But BTW:
I also never understood why mailman has the concept of so called
umbrella lists, which was also build for nesting of mailing lists.

May be I'm too simpled minded?  
But I can hardly imagine the breed of users who want such 
nesting of mail delivery.
