  It was pointed out that brane-anti-brane inflation without warped geometry is
not viable due to compactification effects (in the simplified scenario where
the inflaton is decoupled from the compactification moduli). We show that the
inflationary scenario with branes at a small angle in this simplified scenario
remains viable. We also point out that brane-anti-brane inflation may still be
viable under some special conditions. We also discuss a way to treat potentials
in compact spaces that should be useful in the analysis of more realistic brane
inflationary scenarios.
