The rest of you probably aren't smart enough, but I can usually figure out which "AB" people are talking about through this thing called "context." For example, if someone says "AB, playing in the summer league, made 3 out of 5 three pointers and threw an alley-oop to Steve Novak" I can infer that the poster is talking about Aaron Brooks, because Another Brother does not play basketball for the Houston Rockets. On the other hand, if someone says "AB is going to be on Late Night with Conan O'Brien, and he will be using some of his classic comedic material" I will assume ther person referred to is Another Brother, because he is a comedian, while Aaron Brooks does not go on live television to tell jokes. Again, all this is complicated and hard to comprehend, but that is how I would handle the problem.
Until such time that you choose an unpronouncable symbol for your name, you can always use αβ in the interim ... In addtion, the usage of Greek letters may make you more popular among sorority and/or fraternity members (but perhaps more disliked among V-span haters, who will respond negatively to anything Greek) ... it's a trade-off ...
