Heartily second the idea of Persona being re-rolled as classic login replacement, with emphasis on standardizing login best practices, such as password strength, password format disclosure, input naming that plays nicely with other password management systems, etc. The sheer amount of cruft and non-standardization involved with basic site login actively discourages user involvement. If Persona solved that unobtrusively, they would be adopted and evangelized all over the land.
