[jboss-user] [Clustering/JBoss] - Custom implementation of FirstAvailable Load Balancing Polic

I'm trying to create a simple Jboss cluster with 2 nodes running JBoss 3.2.4 with the farming service activated, but I have a lot of legacy restrictions.
The load balancing policy I need to use is the FirstAvailable, but I need some enhancements.
The FirstAvilable documentation says:
anonymous wrote : One of the available target nodes is elected as the main target and is used for every call: this elected member is randomly chosen from the list of members in the cluster. When the list of target nodes changes (because a node starts or dies), the policy will re-elect a target node unless the currently elected node is still available. Each client-side interceptor or load balancer elects its own target node independently of the other proxies.
This behaviour is perfect for my cluster except for one thing. I need some of this enhancements:
Option 1) When the list of target nodes changes, the policy re-elect ALWAYS a target node
Option 2)The policy re-elect a target node every X timeout
Does anyboy know how could I do this?
I tried storing a session time in my custom policy re-implementing the writeExternal and readExternal methods from LoadBalancePolicyEx unsuccessfully.
