I do have a suggestion. Write a program that takes the configurations for
all 100 (1000, 10000) machines from a file or database, generates the
configuration files, and then distributes them to the nodes using an agent
or something similar. The config files are kept under configuration
management centrally and pushed out to nodes when changes are made.
