A member on the node can also delegate a subset of rights (such as a sub-directory)
to another.
This security solution is fair, but not perfect yet. The system gives the right to the users to
decide which level of security should be applied. The user can choose a proper cryptographic
algorithm to encode the important files. He can also apply a digital signature or encrypt his
transiting message, before using SSL, to improve security. The system only provides fundamental
solutions, which should be necessary to all the users. Additionally, no centralized
components exist, which means that each node is isolated. The user has difficulty in finding
the location of services. In the future, efforts will be made to provide a grid service broker or

services are provided. Even though the broker might have some characteristics of centralized
control, the flexibility and scalability of distributed administration will still remain.
