CounterParty XCP is here too. It enables asset issuance, stock distribution, exchange & dividend payments. completely built on top of bitcoin protocol layer. arguably more mature than any of the colored coin implementations currently being trialed, including chroma, SF, etc.
ActiveMining could well be forward thinking, emerge in the bitcoin 2.0 saga by leading the way with the first truly decentralised asset

Disclaimer: The code being released here is of alpha-quality and under heavy development. You should expect to encounter significant bugs when using it. It is even possible that a bug might cause you might lose some money. The Counterparty team will do everything in its power to prevent this from happening, but this technology is very new, and the implementation is not yet well-tested. In particular, we may at some point have to change the Counterparty protocol in a not backwards-compatible way, if such a change is necessary to fix a bad bug or an exploit. As always, don't invest more than you can afford to lose.
As with CC I wonder who is responsible for support?
Can support guarantee that if we encounter a high impact bug of some sort it will be sorted out?
If not, please don't gamble, wait until it is stable!
