Do we need to handle the case in which two or more peer have the same nickname?

[DiogoSantoss]

We probably should, just not sure what to do in that case. We could change our own by adding some suffix to the nickname. I don't know if we consider malicious nodes in this case.

I think we can't do much about this.. just allow them to do that.
