you should be able to feed other kinds of session-like objects into scoped_session(). Look at its source, it doesn't do much. Ignore everything it says about "extensions" too, that's all going away. You could reuse and extend its approach using the instrument() function to add your own accessors to it. > > Thanks, Torsten > > -- > DYNAmore Gesellschaft fuer Ingenieurdienstleistungen mbH > Torsten Landschoff > > Office Dresden > Tel: +49-(0)351-4519587 > Fax: +49-(0)351-4519561 > > mailto:torsten.landsch...@dynamore.de > http://www.dynamore.de > > Registration court: Mannheim, HRB: 109659, based in Karlsruhe, > Managing director: Prof. Dr. K.
