Yes, what you're trying to protect against is traffic analysis. The only
way to do this is to have a messaging app that will send random messages
to random users to cloud the waters. This would have to be don't in a
manner which would remove statistically meaningful information from
distribution of messages send and received by users of the system, ie
flatten the distribution curves for user-to-user messaging. This would
be easier to do when combined with onion routing across multiple
separate legal duritictions .
