Find a good way to deal with event loss

```
With UDP, messages get lost. TCP however, would introduce unpredictable delays. 
Implement something like a thin security layer that makes the protocol more 
reliable without adding delay, eg running message numbers for figuring out 
message order and ACKs to ensure a packet arrived.
