I see the solution fairly simply.  we need a way for a FOAF file to state
that it trusts another FOAF.  for instance, in Bob's FOAF, he might have
something that states "This FOAF trustsHighly Eric's FOAF"  and my FOAF
might also have something that says "I trustAveragely Dave in GUI Design",
which would mean that Bob could then apply a level of trust to Dave, because
his FOAF trusts the information in my FOAF...  What's we're really needing
to measure is how much any given person trusts a given FOAF, so I think this
would work well.  Jen's trust module could be used in this manner, and we
would be able to build a large trust network.
