We intend to illustrate in this lecture the possibilities opening up at machines planned for the nineties for low--energy kaon--nucleon interactions, keeping the focus on the theoretical problems they should help to solve. We shall deal here only with the $ϕ$--factory DA$Φ$NE$^1$ and consider, for brevity, interactions with light, gaseous targets, using gaseous $H_2$ as a benchmark for which to estimate the rates to be expected in a typical apparatus.20 pages, PlainTex, DFUPG-54-92Nuclear TheoryHigh Energy Physics - Phenomenologytext
