BuddyPress.org

I just talked things over with Andrea; I’ll be releasing a plugin shortly with the code snippets posted above.
I’ll add private message username overrides as well. Is there any other place where display names are used?

However, I do see some benefit with leaving the “Name” field on the registration page. The name gets displayed on a BP profile – eg. http://testbp.org/members/andy/profile/.

Also Twitter does something similar; they add the “Name” field to the sidebar of each profile.

FYI, first name, last name and nickname fields are not added to the registration page unless you manually created them as xprofile fields. Look at testbp.org’s registration page for an example: http://testbp.org/accounts/
