Wanted - Best Practices for Configuring and Using the new R2 WCF Adapters

I am looking to document "best practice" experiences in configuring and using the new R2 WCF adapters so others can learn from the mistakes/recommendations made by others. If you have anything to contribute I would greatly appreciate it.  Either post recommendations here or email me directly at mmckeown@microsoft.com with "WCF Adapter Best Practices" in the heading. I am working to compile a list and publish it by end of October. Thank you!
