I seem to recall that nnfolder pretty much works with compressed folders
already; have you tried it?

It's been a while since I use nnfolder, but I used to, and I often
compressed old folders.  As I recall, you just had to (1) compress the
folder's mbox-file (using gzip, which automatically renames the file
from `foo' to `foo.gz'), and (2) rename references to it accordingly
(from `foo' to `foo.gz') in various places; the active list is the only
one I remember (file called `active' in the same directory).

[Also, it might depend on having emacs `auto-compression-mode' enabled.]

It might be nice if Gnus offered a `compress nnfolder' command that
automatically performed the necessary steps.
