Dotcom is our factories, producing top-of-the-line high quality tokbands (although we're not really sure yet what a tokband is).
Amazon is our sales server, responsible for the transactions and interfacing with our factories.
Meister is our own webserver, running PHP-scripts and serving static pages for our dear customers.
Red Chief is our proxy, responsible for keeping control of our network and keeping our internal network safe from bad and evil stuff.
