  The original plan of a vigorous program of frontier physics at LNF, based on
the phi-factory DAFNE with the KLOE detector, has not yet reached its major aim
in the study of discrete symmetries in the neutral kaon system. It has however
led to the education of a new generation of particle and accelerator
physicists. With such invaluable human resources it seems appropriate to
consider a renewed effort in achieving much improved collider performance. It
will be argued in the following that it is still possible to envision a program
of superior quality physics, requiring several years and broad enough to
justify a new collider operating at the phi-meson mass. It remains of paramount
importance that the program covers topics of fundamental interest, with many
collateral avenues well connected to the ultimate goal, a most sensitive test
of CPT invariance. The appropriate time frame for these ventures to be
successful is quite well defined, in view of the large LHC effort to begin
towards the end of the present decade.
