  As a future upgrade of the Frascati phi factory DAPHNE an increase of the
center-of-mass energy of the accelerator up to W=2GeV has been proposed
(DAFNE2). In this case the hadronic cross section in the energy range between
1-2 GeV can be measured with the KLOE detector. The feasibility of these
measurements and the impact on the hadronic contribution to the anomalous
magnetic moment of the muon are discussed. The possibilities for an energy scan
are compared with the radiative return technique, in which the accelerator is
running at a fixed center-of-mass energy and ISR-events are taken to lower the
invariant mass of the hadronic system.
