I always liked the idea of standardizing on notes with the formula Cx = 2^(x+4)Hz. In reality it's fairly arbitrary, but in this method the frequency would follow numbers familiar to programmers, e.g. C5 = 512Hz C6 = 1024Hz C7 = 2048Hz In such a method, 'A' would be closer to 431Hz, so slightly flatter than the 440 we use now.
