We anticipate the possibility of deploying Lightstreamer in a web server farm (initially for redundancy purposes but presumable later also for capacity reasons). If Lightstreamer is to be deployed behind a NLB, are there any specific considerations?

For example:
  1. Which load balancing method can be used? For example could we use Round Robin or would Server Affinity be required?
  2. Are there any performance or resource implications we need to consider when choosing one load balancing method over another.
  3. Unless I missed it in the documentation there does not seems to be any built in functionality to keep multiple Lightstreamer Web Server?s in sync. Is it true to say that responsibility fall to the Data\Metadata adapters?

Could you guide me to more detailed documentation on how to deploy Lightstreamer in a clustered/farmed environment?
