Are the problems in designing large backends really in the backend? Most problems with large backends are due to the design of Gnus, not the backends. NNML scales linearly with the number of messages in the group, does it not? Gnus definitely doesn't scale linearly, so redesigning something to get support for large mail/news backends should go into Gnus, I think.
