We updated the I2NSF problem statement to reflect the narrower scoped charter. 

The primary issues and challenges facing NSFs hosted by different domains are:

      3.1. Challenges Facing Security Service Providers..............5
         3.1.1. Diverse types of Security Functions..................5
         3.1.2. No Standard Characterization of NSFs.................6
         3.1.3. More Distributed NSFs and vNSFs......................7
         3.1.4. More Demand to Control NSFs Dynamically..............7
         3.1.5. Diverse Interfaces to Control and Monitor NSFs.......7
         3.1.6. Lack of mechanism to monitor the behavior of NSFs....8
      3.2. Challenges Facing Customers...............................8
         3.2.1. Need to integrate on-premises NSFs with Remote NSFs..8
         3.2.2. Today's Policy Expressions are Vendors Specific......9
         3.2.3. Difficulty to Monitor the Execution of Desired Policies
         ...........................................................10
      3.3. Difficulty to Validate Policies across Multiple Domains..10
      3.4. Lack of Standard Interface to Inject Feedback to NSF.....11
