Currently setting a policy member to weight=0 removes that member from policy tree. There are situation when you want to have members with weight 0, for example you want to serve EU traffic from EU ip's but when they are down you want to automatically move traffic to US. This can be done by setting EU weight > 0 and US to weight=0. We should give each policy member an enabled flag which acts just like the current weight=0.
