In section III.B we outlined the various types of integration scenarios we plan to support: between different session management schemes, between sharing services and VE services, and so on. Once the exact set of tools and the services they offer has been finalized, we propose to identify an initial set of concrete integration scenarios involving the use of these tools. We propose to finish this task in the first three months of the project. It will involve installing the various tools at the sites participating in this project and comparing and contrasting the services they offer. We expect this set to continuously involve as we better understand the integration problem.
