Ok, I'll put "write another trust model" on my todo-list. But not under
the "I need this badly" section. Rather under "If I have nothing more
useful to do".

Over the past few days' I've been thinking about it, and it seems to be
a very complex problem. Mostly because the quantitiy involved (trust) is
not very well defined (which I consider a feature in general, but a bug
in this particular context).
