Just because it can be done with Bitcoin, doesn't mean it should be, especially if it doesn't fit particularly well.  Bitcoin colored-coins solutions require you to involve a 3rd-party software or sidechain, and different crypto-currencies ARE sidechains, they just use economic "free-market pegs" instead of cryptographic.  


People can be hostile to each other when they have financial interests that they perceive to be threatened.  I certainly want Bitcoin to succeed because it is the value base for other crypto-currencies/DAOs/DACs.  Nxt is an account-based decentralized services platform and you use the tokens (NXT coins) to pay for a variety of transaction types with different fixed fees.  That is nothing like Bitcoin.  Nxt has a lot of digital asset features native in the protocol and you can already do multiple types of deferred & voting based transaction commitments on-blockchain.  If it provides the features you need, at least try it out for free on Nxt testnet.  Nobody is asking you to stop using Bitcoin, and you can always hash your own checkpoints into the Bitcoin blockchain for extra security if you feel guilty.
