  The tau anomalous magnetic moment (a_tau) and electric dipole moment (d_tau)
have not yet been observed. The present bounds on their values are of order
10^-2 and 10^-17 e*cm, respectively. We propose to measure a_tau with a
precision of O(10^-3) or better and improve the existing limits on d_tau using
precise tau- -> l- nu_tau \bar{nu}_l gamma (l=e or mu) data from
high-luminosity B factories. A detailed feasibility study of this method is
underway.
