Why is that a hard problem? 

There are some parts that are simple:

  -  a UI to show what you are logged in as and to enable the anonymous mode
  - Tying cookies and SSL sessions to identities

The hard problem is information leakage, but that is something one can build up over time. How far you go there depends on how much you want to protect identities and cross referencing.
