It seems like "TypeKey" does allow "." character (ex:User.ID) in the "User ID" but when a comment is posted using the typekey login, the profile name is linked to http://profile.typekey.com/User.ID/ which when clicked leads to a "404" error.
The TypeKey folks need to fix this issue by either linking the profile to http://profile.typekey.com/UserID/ (which infact works) and restrict the use of special characters during registration if they cannot be handled by the TypeKey system.
