It really depends.

In my method, the Packages file for each day needs to be kept
at the server, i.e. 1.6 MB per day of backlog to diff against.

1 week = ~10MB
1 month = ~40MB

And doing this all for all arches, it gains

1 week = ~120 MB
1 month = ~500 MB

So, the server (possibly ftp-master) needs to carry around
500MB worth of Packages file to create the diff if we want to
make a diff for a month's worth of data.
Shifting that much data would probably be an overkill 
considering that many people do update their packages file
more than once a week (or in fact run a cron job of doing
apt-get update).

The advantage of using md5sum, is that 
it doesn't depend on meta-information like "date", which might be
screwed at some mirror for some reason.
