Michael Eisen and Leslie B. Vosshall have self-archived "Coupling Pre-Prints and Post-Publication Peer Review for Fast, Cheap, Fair, and Effective Science Publishing."
Here's an excerpt:
Pre-prints will be not be embraced by biomedical scientists until we stop treating them as "pre" anything, which suggests that a better "real" version is yet to come. Instead, pre-prints need to be accepted as formally published works. This can only happen if we first create and embrace systems to evaluate the quality and impact of, and appropriate audience for, these already published works.
