The KLOE experiment is currently taking data at the electron-positron collider DA{phi}NE, the Frascati {phi}-factory. At the end of this run, we expect to have integrated 2.5 fb-1 of collisions at center of mass energy W {approx} M{phi}. Large samples of light pseudoscalar and scalar mesons are produced through {phi} radiative decays. A summary of the measurements in progress on the previously collected 450 pb-1 allows us to quote the expectations on the entire sample. KLOE has also proven the feasibility of precise measurement of the hadronic cross-section {sigma}(e+e- {yields} {pi}+{pi}-) in the region 0.33 < M{sub {pi}}{sub {pi}}{sup 2} < 1.02 GeV{sup 2}, extracting it by the measurement of the {pi}+{pi}-{gamma} cross section at small photon angles. Prospects for the entire sample and the feasibility to extend such a measurement down to threshold are presented.
