What is interesting to me is that in the (IMO very unlikely) event that Nxt has technical promise, then as soon as the code is open-source it will be possible to create Nxt-clone using the
spin-off mechanism and immediately bootstrap the clone with a more efficient distribution than Nxt-original.
As I understand it, the Nxt code is modular. The core, including the PoS stuff, will be open-source, but some of the services built on top will not be. The Nxt devs believe a lot of their value is in the services - things like the Asset Exchange. So the clone won't include all of Nxt.
Asset Exchange is in the core and is open source.
Third party services (like muiltisig gateway for othjer cryptos) may or maynot.
