We consider the issue of determining the D0– width difference ΔΓD experimentally. The current situation is reviewed and suggestions for further study are given. We propose a number of D0 decay modes in addition to those studied in the recent E791, FOCUS and BELLE lifetime determination experiments. Then we address prospects for determining CF-CDS strong phase differences, like δKπ which appears in the CLEO study of D0→K+π− transitions. We show how to extract δK*π with CDS data and furthermore show when D→KLπ data becomes available that δKπ can also be obtained.
