Web trust models seem to be a more general approach to the problem
and I have yet to find a non-web trust model which could not be emulated
using a web trust model (you just have to be careful about stipulating
who is the "center" of the web and the relationships that can be drawn
from this.)  OTOH I have not done a complete study of all of the possible
trust models which might be necessary, is there an example of a trust
system which cannot be expressed through a web model that someone can
present?  If the constrained web model has the capability of being able
to express all other models then it seems like a good system to use...
