It is technically possible to add arbitrary data to a transaction with OP_DROP, but it isn't widely supported enough, and most tools for exploring the blockchain won't display it in a convenient manner.
However, due to the changes in the way bitcoin-qt 0.8.2 handles dust outputs, I will probably need to change it to a different method in the future. For now, there are still a lot of miners that accepts those transactions.
