Unfortunately, they also become fertile grounds for hackers to deploy mal- ware. How can the indices of each child VO be meaningfully merged so that a query on the parent VO will almost always find the relevant information contained within? Can a distributed signature be devised to efficiently represent the service data and grid services associated with a group of VO’s? (b) Dynamic reconfiguration.
