WotLK Stupid question - crossrealm trading

[Vilya]

Hey, I have a stupid question. As far as we know, we can't trade/send items to characters from other realm.

However, did someone tried (as for example Icecrown player) trade in BG with character from Blackrock?

What is the error (or there isnt any, lol) when You trade in bg with char from other realm and he tries to give You gold or BoE items?

There is an error and you can't open trade with people from other realms.

You are only able to trade with other realms conjured items (Food, Healthstones, etc...)

I think they covered up that issue in the early days, Imagine trading with BlackRock players where you start with 200k gold.

Yea I know it should be forbidden, but I accidentaly clicked trade at other guy from different realm in BG and the "trade window" just opened normally - I'm 99% sure for it. I was wondering, how the game would react if You would try to give some gold between blackrock-icecrown etc.

If someone could make a screen/video of this action, I'd be interested :)
