For the love of all that's Good and Holy...
Will someone in the OSS community please develop a comprehensive, enterprise-ready, robust shared calendaring solution that integrates cleanly with the obvious-good mail handlers (postfix+dovecot and exim) so people will stop running freaking MS products with terrible email servers and terrible web interfaces just to get a calendar for their humongous organization that desperately relies on the coordination of shared calendaring?
@wbr It might be...toots came in out of order, so I'm not sure whether I'd said this, but I have concerns about scale.
Some of the orgs I'm thinking of have hundreds of thousands of active users.
@HedgeMage Is kolab.org not what you're looking for? It supports calendaring for people and resources.
