To follow up, im not necessarily saying that my solution is what we have 
to use, but it is the only solution so far that does actually completely 
solves the problem at hand (i.e. actually works with privacy lists in 
place), and to me at least seems a nice neat and simple solution (isnt 
that the sort of protocols we are aiming for?), but everyone is of 
course free to make their own suggestions :)
