I can try. This is what you wrote earlier:

quote = <<END_OF_QUOTE
in = File.open("/var/mail/joe")
out = File.open("/home/joe/mails.zip")

mbox = Archive::Reader::Mbox.new(in)
zip = Archive::Writer::Zip.new(out)

mbox.scan do |entry|
zip.add(entry)
end

The `add' method from Archive::Writer will see that we're trying to
write on a zip and that we have a Mbox::Entry#to_zip method, so will
use that, and we'll have converted from Mbox to Zip on the fly.
END_OF_QUOTE

I think this example is basically fine, except your comment about how
zip.add(anEntry) will recognize that Mbox::Entry has a to_zip method. This
should not be necessary because Entry is (or should be) an object that
implements an interface that is common for all archive entries.

Ok. It seems to me that your design is heavily influenced by the structure
of tar.gz files, where the archive is compressed, instead of the archive
containing compressed entries (I think this is a short-coming in tar.gz
files). Are there other archive types that are as expensive to scan? What
other archives would benefit significantly from cached (to disk) maps of the
archive? Or from the iterative access, where you have to iterate over
entries, even if you know the id or name of a particular entry that has your
interest.
