Not true. There just needs to be an association between packages
file and CD label.
A file in each directory that says which CD the packages are on
would be sufficient.
E.g.
/.packages/non-free/Packages.gz
/.packages/non-free/media (contains "CD 2")
/.packages/main/Packages.gz
/.packages/main/media (contains "CD 1")
Or something like that.

Sure. You've done the work, and it will be fine for this release,
but it's worth discussing ways we can improve on it in future.
The basic scheme is fine, it's just the X-Media can be put elsewhere,
which means the same pacakges files can be used everywhere.
It would be *less* work to actually leave dpkg-scanpackages as it
is, and just add this change to the multi-cd method. But *more*
work has already been done, so it isn't necessarily worth changing
now.
