Query: Projective and Reedy model category structures for (infinitesimal)
  bimodules over an operad   We construct and study projective and Reedy model category structures for
bimodules and infinitesimal bimodules over topological operads. Both model
structures produce the same homotopy categories. For the model categories in
question, we build explicit cofibrant and fibrant replacements. We show that
these categories are right proper and under some conditions left proper. We
also study the extension/restriction adjunctions.
