Well, right now the weight is just used to find the best path, but it should 
be easy to add another if statement that drops a (otherwise valid) chain if 
the accumulated weight is above a certain threshold. Then all you have to do 
is to make the weight of all plain text filters exactly the threshold. If one 
more filter is added the chain is invalid.

Ciao,
Werner, who unfortunately doesn't have the time to do that himself :-(
