The SM predicts zero value for \bf CP & \bf T violation in the decays of τ leptons -- except τ- → νKS [π-/π-π0 ...]. Our community could establish impact of New Dynamics (ND) in a \bf CP asymmetry in a semi-hadronic τ transition and later in a second one. To be `practical', I suggest to our experimental colleagues to probe τ- → ν K0 [π-/π-π0/π-η]and τ- → νK-[π0/π+π-/η]. While I had mostly given comments about \bf CP violation in τ transitions, some theorists have shown how ND models could produce \bf CP asymmetries; I will discuss these ones, although sometimes I am not a true theorist, but as a phenomenalist here. I can hardly `dream' that \bf CP asymmetry in τ decays could connected with our huge asymmetry in `our' matter vs. anti-matter.
