  On the basis of a calculation of the exact interliquid hopping rate and an
approximate single particle Green's function, we present new evidence for the
existence of a phase of relevant but incoherent inter-Luttinger liquid
transport. This phase of ``confined coherence'' occurs when the Luttinger
liquid exponent alpha satisfies alpha_c<alpha<1/2. We argue that alpha_c is
strictly bounded above by 1/4, and is probably substantially smaller,
especially in spin-charge separated Luttinger liquids. We also discuss
connections with the work of others.
