The rules against IRL item transactions or assets on other games have always been more to protect the players from scamming than anything else. Since there will be no mechanism to facilitate safe trading, the rules will also extend to disallow player A promising to give player B something on server A in exchange for something on server B.
If it becomes public knowledge that someone is trading assets between servers, that will be grounds for banning. We have updated Nodiatis rule #5 to reflect this.
