This is called padding traffic and it's been studied a bit in relation
to systems like Tor. Roger has often said that a conclusion of the
studies was that it's hard to get a lot of privacy benefit from most
padding schemes, but it might be good to know what the state of the
art is in padding attacks and defenses.
