Should ${\bar p}p\to{\barΛ}Λ$ be revived?

The continued interest of CP violation in hyperon decay (as well as many other physics topics that could be addressed by such a facility) suggests that a dedicated $\bar p$ storage ring at Fermilab ought to be reconsidered. With recent and anticipated technical progress, sensitivity many orders of magnitude beyond that achieved in LEAR may be possible, including 10^{-5} sensitivity for the $Λ/{\barΛ}$ CP-asymmetry parameter $A_Λ$.
