You'll be able to add friends at the Battle.net account level and talk to them while in-game whether they're on the opposing faction, a different realm, or another Blizzard game entirely. This is coming prior to Cataclysm.
[...] No one outside of your faction on your realm will be able to communicate with you unless you accept their friend request, or they accept yours. You will still have your normal World of Warcraft Friends list, but we'll be adding in the ability to have Battle.net players on your Friends list as well. The characters on your Friends list will allow the same communication functionality which exists today. It's only when you've confirmed someone as a Battle.net friend that you can take advantage of the additional communication features.
We'll get more into that soon, but it's safe to say in advance that you shouldn't accept a Battle.net friend request from anyone you don't know, similar to Facebook or other social networking media.
