  A sizable excess with respect to the SM expectation has been reported
recently by the BaBar collaboration in the decay rates B -> D(*) Tau Nu,
normalized by the corresponding light lepton modes. A violation of lepton
flavor universality as suggested by this excess could be due to a charged Higgs
mediating these processes at tree level. In this talk we analyze the
implications of the observed excess within the framework of two-Higgs-doublet
models, considering also the bounds from other semileptonic and leptonic decays
of B and D(s) mesons. Prospects for B -> D(*) Tau Nu decays at future
Super-Flavor Factories are also discussed.
