Hi Brian,

Great analysis!

At the moment I see 2 solutions to the performance problem:

1. Create an inproc encrypting/decrypting device, send the messages 
through the device.

2. The one you proposed: Create a specialised "message encrypting 
transport" within 0MQ.

No idea how can this be solved. What about using virtual machines to 
achieve secury multitenancy?
