In my research group (in the School of Computing at Dublin City University), we publish all our papers to our web site and to the university's own research portal (doras.dcu.ie). They are free for anybody to access.
The version we publish is the "camera ready", which is to say the last version we submit for actual publication. It is not, however, the final published version (so, for example, they don't include an Elsevier logo or conference proceedings page numbers). I believe this is legal in our jurisdiction, or at least nobody has called us on it!
