quite a mess that works magnificently

Simulated distributed network with multiple servers and clients, and omission failures (f<n/2). Servers sync state (with at least n-f, for safety) before replying to a client read/write request.
Clients can transfer tokens they own to other clients (using the API that talks to the servers), and can also query the servers for the current ownership state. Initial state: 60 tokens, owned by 6 clients (10 each).
