Zipping streams

Writing the following is easy after glancing through the documentation for conduit:

foo = let src = mapM_ C.yield [0..9 :: Int]
          p0 = CC.map (\ i -> ("p0", succ i))
          p1 = CC.filter odd .| CC.map (\ i -> ("p1", i))
          p = C.getZipConduit $ C.ZipConduit p0 <* C.ZipConduit p1
          sink = CC.mapM_ print
      in C.runConduit $ src .| p .| sink

Neither pipes nor streaming make it as easy to figure out. I must be missing something! What functions should I be looking at?
