We all know that Hidden Services need lots of attention. The crypto needs to improve (upgrade keys to other cryptosystems, fix hybrid encryption, etc.) and the protocol needs to improve (make hidden services scale, oblivious transfer for HS descriptors, prevent DoS attacks, valet services, etc.).
IMO, to properly fix Hidden Services someone needs to think of the big picture and write a "Next generation Hidden Services" paper/essay that proposes new protocols and addresses most of the known problems. Then, after we know how these new changes influence each other, we can start writing proposals and figuring out implementation and deployment strategies. Unfortunately, even though I know that some people are thinking about this, I'm not sure if we will see such a paper soon (within the next months).
FYI, we just started a project on improving hidden service protocol. I am working on ticket #8510 so we can first set up tools to profile hidden service traffic.
That said, we are probably not going to publish a paper within the next months ;p
