Unfortunately not, I have not heard anything from Felipe. I personally don't 
see a good way how this can be implemented, so I'm really interested in his 
approach.

Either that, or:
1) Repost the event in the transition and have an in_state_reaction 
(triggered by the same event) store whatever you need (typesafe), or
2) use triggering_event() 
<http://www.boost.org/doc/libs/1_43_0/libs/statechart/doc/reference.html#triggering_event0> 
(not typesafe)

HTH,
