    This approach will probably scale to reasonable levels. When it
    gets to when you are sending out new keys several times a day,
    then batching the drops may be a viable solution.

At some point though, the process of dropping the new keys becomes
equivalent to a cloud service with knowledge of the content and we
lose end to end.

Can you elaborate on this?  If the drops are encrypted to all of the
posters why does the server know the content?

Thanks,
