Fine!.

It has no sense because Spliter will attend only to peers on list and
request to be included in the team.
We did not think in a DoS by repeating a lot of inclusion requests. 

Other peers will only attend to peers in their lists.

In this version there is not such functionality. The aim is to make a
very simple protocol by reduce computation and communication at peers.

The goal is to have the Spliter, Trusted peer and malicious
functionalities in order to perform several configurations and get
statistics about the efficiency of the expelling system.
For instance, play with different ratios of trusted and malicious peers
and different types of attacks.

You know attackers are smart, so you have to think as them. For
instance,  a selective attack until detected can avoid to poison chunk
for the now known trusted peer. If there is just one, malicious can
survive, or not?

Thanks to you.
