I love this idea. How hard would it be to adapt it to eprint.iacr.org?
I need paper metadata to be available in a structured format. I currently support the "arXivRaw" metadata format of the OAI-PMH protocol [1]. Unfortunately I didn't support RSS yet. Are you one of the maintainers of iacr? What is the size of its userbase?
Not one of the maintainers, just an avid follower :)
