Well, that's okay, since SETI is looking for deliberate signals, not
indirect chatter or accidental spillover.  If you want to talk to the
widest possible audience, you use the simplest means of communication. 
By definition, people using super wiggy zeta particles to communicate
are not going to be found by SETI, but that's okay, since that's not
what SETI is looking for.
