This is the approach we take. It works well so far, both for "good" and 
"bad" events. It does have the disadvantage, which Ingo also pointed 
out, that the components either need to be designed with the method in 
mind or need to be some form of stateless. In my opinion, however, if 
you are doing proper loose coupling then it's not *that* special, so 
components that are not designed like that probably need fixing. ;)
