SEPMs (RU7 MP1) not load balancing

We followed all of Symantec's instructions and best practices for load balancing our six SEPMs.

I would like to know two things:

1. Has anyone had success with actually load balancing SEPMs. And I don't mean if you are a Symantec employee?

2. If you had success with load balancing your SEPMs, did you use some third-party solution, such as Network Load Balancing, or DNS round robin.

I would love to hear about this. For the longest time, our SEPMs have not load balanced and when we open ticket with Symantec, we are yet to hear any solutions.

Kindly help!!!!!

P.S. And please don't say to upgrade to SEP 12.
