Tim’s post here points out that sharing copyright with journal publishers does come with strings attached – as in you might not be able to submit it to an electronic repository (as hypothesised here a day or so ago).
Might be interesting to see what the definition of a repository is. Tim and co’s idea seems to be for a place to upload files to. I wonder if instead each person is responsible for hosting the files (via department space or their own domain name) and then the “repository” merely provides an indexes to those files.
