[Nel] Synchronized Messages?

[Walker]

hello,

For the fairness issues in online multi-player games, Is there any
synchronization mechanisem in NEL?

Let's say that in a Capture-The-Flag scene:
Due to the network latency, 

1) Some players can take early actions before others have chances to
react, because they got the message earlier.

2) The server may handle user A's action message before from user B's,
even user B hitted his keyboard before user A.

This is my question, thank you!
