Adaptive Elo rating without centralized server

[x3oo]

Dear OpenRa-Community
I hereby suggest to implement a decentralized Elo-rating algorithm for openra without the need to collect statistics on a server.

The algorithm is implemented as described in the linked blog article. Then the calculated elo ratings for all played matches including players are saved LOCALLY instead on a server. So everyone is doing the Elorating only locally for themselves and when you join a server you can transmit local elo ratings and recalculate them. basically this is how its done in chess and it works decentralized too.

Something in that vain was done with http://oraladder.net/ see http://blog.pkh.me/p/28-building-a-comp ... penra.html for a making of. It uses TrueSkill which unlike Elo supports games with more than 2 players.
