Page 229 of the 20thEd says, "You encrypt a file, set of files, node, or communication link."
With this is mind, can you encrypt a bionode?
And an even more crazier idea, if you can, what happens tor spells like Control Actions, Control Emotions, Control Thoughts, Influence, and Mind Probe.
Since all of these spells affect the mind, and would seem to require some access to the mind to give commands or understand what's going on inside it...
Just thought this was an interesting idea.
