I never remember the difference. Seeing as I said TLS in

, assume I'm confused.

This has been discussed before. See
   http://www.eros-os.org/pipermail/e-lang/2008-February/012500.html
and the thread around it.

The summary is, you can't actually dispense with encryption unless  
you have a set of vats you are mutually reliant on for not spoofing  
VatIDs (which is quite feasible, but needs extra code in the  
implementation).
