apologies if we've covered this already and more recent parts of
the debate have displaced it in my short term memory, but can you 
give one or more examples of which messaging requirements you have
which cannot be satisfied by PLASTIC?  It would be good to add a use
case or two which fits this description to the wiki page:

so we can make sure that whatever we end up with does actually solve
the problems which we need solved.  I've just (belatedly) added one
of my own which represents one of the scenarios which PLASTIC can
handle well and which I think it's important that any replacement of
it can do too.
