Hey, that's imporant too :)
It's not hard to invent a reason for -k if we need one. E.g.
the protocol is specific to the Kemari project, right?
So the text could be 'Fault Tolerance mode (using Kemari protocol)'
to avoid potential confusion with other fault tolerance solutions
if we ever get them, and the option stays -k :)
