We’re also a community of real-world people based round a real-world place/resource so it doesn’t make sense to have two identities.

From version 3.0, my Real Name plugin has an optional Real Name only mode not only for topic pages but for profile pages and usercard popups (mini-profiles) too. It also supports Real Name only mode for Accepted Answer plugin.
