One of the featured planned for the next major content patch (3.3) is the ability to form groups across multiple realms. It's unclear at this point whether it will be through the LFG tool and if it will be limited to realms in your battlegroup, but it's a definite improvement. Additionally, the friends tool is being overhauled to include all battle.net accounts, allowing chat between any accounts, regardless of which server they're on or which game they're playing.

Also, the next expansion is going to update Eastern Kingdoms and Kalimdor so as to allow flying mounts.
