@fruchtblase Hmm. Well, here's the basic version. Tis is like 3 or 4 years old and I haven't put much though into it lately, so don;t take it too seriously. Hopefully you'll find it interesting, though?

Basically, a system of small enterprises, operating without money. Instead, they "Subscribe" to a Logistics Enterprise, that takes care of distributing goods between them. If you don't like the Logistics enterprise you've been working with, switch to a different one. The logistics can even trade amongst themselves, or an enterprise could subscribe to two different ones. In essence, a number of parallel, competing and cooperating planned economies.
