Here is an example shared configuration for knife. You can drop this off in your chef-repo/.chef/ directory, and multiple developers can use the same knife configuration to interact with more than one Chef server, or the Opscode platform.
By using Bash functions and environment variables we can change the chef server, which knife is configured to use, on the fly.
NOTE: knife will probably ignore your ~/.chef/knife.rb once you begin using a shared knife.rb in your chef-repo directory.
