Why Litecoin though? Bitcoin has so many obstacles on its path that it makes me think alternative currencies attempting to solve single issues do not contribute to the crypto-currency concept that much (they do contribute to research and development though). If it's an essential feature, it would and should be embedded into Bitcoin, otherwise there would be an inflation of crypto-currencies that appeal to particular use cases. For instance, scalability is such an enormous issue that it renders all diversity in currently implemented alt-currencies insignificant.
One essential feature that probably will NOT be a priority feature for Bitcoin is sheer official worthlessness, like baseball cards before they took off, like comics before *they* became collectors items, worthless game-tokens that game-players can have fun with and maybe, many years later, find are worth some silly amount of money possibly for quite silly reasons.
Bitcoins are more and more unsuitable for games the more they try to be "real money", because the more "real" the money the more "gambling" type fuss gets dragged in to spoil the game(s).
We *need* poker-chips that don't turn any and every game that finds some use for them into "gambling" merely on account of the chips happening have the word "poker" associated with them in some way.
