DA\PhiNE at the c.m. energy of the ϕis a relatively clean source of low-momentum charged and neutral kaons. As such, it can allow experiments unthinkable of at conventional kaon beams. This talk is dedicated to a presentation both of this viewpoint and of the physics that could be learned in this way.13 + 1 PlainTeX pages, pres. at "Meeting on e^+ e^- Physics Perspectives (non-K Physics)", Frascati Jan. 19-20, 2006; v2: unchanged paper, only a typo in the DISPLAYED abstract correctedNuclear TheoryHigh Energy Physics - PhenomenologyNuclear Experimenttext
