•Is there a Common View of Control and Resource Allocation ?
•Can we Implement a Managed Environment Across Multiple Networks?
•Is Interface Definition Well Resourced and Understood?
The Technical Challenges
•How will Cost Sharing Develop?
•What is the Correct Architecture?
•Will GRIDS and Networking Converge on Technical Solutions?
The Overall Challenges
