So, with the details from a matchFoundMessage(2 players) i create a Challenge  AND a RTSession.

After ChallengeStartedMessage i have  both players successfully participating in a that Challenge.

Simultaneously both clients connect to my RTSession controlled by an RTScript.

When the RTScript decides  who wins  i want to inform the Challenge who the winner is through my RTScript.

Im sure it is possible. Could you give me a hand?
