Office+encryption (Score 1)

This is similar to using PGP or GPG to encrypt files and communications. For those of us who try and use these products, the frustrations are the extra steps required to use these tools, the huge amount of trust required in readers, and lack of standard installations.

It is almost not worth encrypting communication until DRM is in place. It is because office applications don't understand encryption that copy-paste, printing and forwarding can still occur today. I certainly hope that other popular encryption products jump aboard.
