That is great :-)
We originally thought, that people should (very formally) claim authorship of the imported papers
http://www.physicsoverflow.org/18022
but then realized that this procedure is a bit too cumbersome and obstructive
http://www.physicsoverflow.org/22717/automatic-import-automatic-authorship?show=22717#q22717
So if you like, I could assign you as the author of the paper right away, and to start the discussion, you could for example edit the submission to put down a more extended summary and additional comments/explanations than what can be found in the abstract on the ArXiv.
