I think you can write the third function in an even shorter way with Future.traverse instead of Future.sequence:
Future.traverse
Future.sequence
Future.firstCompletedOf(Seq( Future.traverse(Future.firstCompletedOf)(Seq( Seq(web(query), webReplicated(query)), Seq(image(query), imageReplicated(query)), Seq(video(query), videoReplicated(query)) )), failAfter(timeOut) ))
I didn't expect this, but I discovered that Future.traverse is really handy in lots of situations.
