Since I am using more than only one MacPorts installation for testing purposes I'd love to have the ability to have a local mirror which would be accessed by all my different MacPorts installations prior to accessing some remote server. Does such an configuration option already exist? If not, I guess, it would be a great feature, don't you think?

Are you aware of the MASTER_SITE_LOCAL environment variable? Personally
I just run squid.
