That's a neat idea, and shows off Seaside in interesting ways.  Thanks. 
  In terms of implementation, though, the manual swapping of root etc 
seems unnecessarily complex.  Couldn't you have done this?

SeasideLoginSession>>user
   ^ user ifNil: [user := root call: SeasideLogin new]

And then in SeasideLogin>>handleLogin, at the end, instead of directly 
sending #user: to session, just #answer: the user object.
