I might have missed the announce list message, but checking eprints.org  (esp. the download page  it appears that version 1.0 is ready to go. According to the main page, "An earlier private beta release of eprints met with unanimous approval. The first complete operational release is available (for free, of course) as of December 1 2000." Of course, the Open Archives  standard is about to change as of mid-January (at the public meeting in D.C. ), when they will release the next version of the OAI spec. So eprints will have to change pretty soon, but it looks solid already otherwise.
