The company where I'm currently working has a very strict security policy and Composer is not allowed to access any host outside the company intranet. Each developer gets it's own VPS for development within the internal cloud that has php, composer and other dev stuff preinstalled, but there's no route to internet from VPS. Workstations have limited internet access only for email and browsing the internet. We managed to make Symfony and composer play together with Satis available on an internal server. It's annoying to manage Satis static dependencies sometimes due to strict package white list standards but it generally worked... well, untill Symfony Flex came up and http://symfony.sh which is not available to our internal workstations and dev environment.
So is there a way to run a flex server on premises or to reuse a local Satis repository somehow to deliver flex recipes?
