I don't see the connection between rtti/virtuals and event deferring. 
Anyway, in case of Boost.FSM virtual functions are only used for enter 
state handlers in case of run-time version of state switching. Type info 
is used for convenience only - it provides default state names and 
diagnostic information in case of exceptions.
