  We reanalyze the allowed parameters for inhomogeneous big bang
nucleosynthesis in light of the WMAP constraints on the baryon-to-photon ratio
and a recent measurement which has set the neutron lifetime to be 878.5 +/- 0.7
+/- 0.3 seconds. For a set baryon-to-photon ratio the new lifetime reduces the
mass fraction of He4 by 0.0015 but does not significantly change the abundances
of other isotopes. This enlarges the region of concordance between He4 and
deuterium in the parameter space of the baryon-to-photon ratio and the IBBN
distance scale. The Li7 abundance can be brought into concordance with observed
He4 and deuterium abundances by using depletion factors as high as 9.3. The
WMAP constraints, however, severely limit the allowed comoving (T = 100 GK)
inhomogeneity distance scale to (1.3 - 2.6)x10^5 cm.
