For those not following NXT, I have been divorced from NXT.

A passport system for assets that allows the asset holder to decide the blockchain they want to reside in. While the PoS mechanism is fully protecting the NXT holders as designed, it allows the creation of a hardfork that ignores other parts of the ecosystem, like assets.
James, have you considered starting a 'relationship' with Qora after your divorce from NXT?
I think you would find the Qora dev team very easy to work with on something like your asset passports protocol.
The passport systems requires that any blockchain that wants to participate would be able to. It is an interop standard. I am working on a method that will allow weaker chains to utilize BTC for security. Not for all tx, but for a backstop past which all the tx in that chain would become permanent
But in all the scenarios, iguana must be fully working first, so for now I will be slogging through all the bitcoin rpc and make sure they are working.well almost all, there are a few RPC that are not relevant in iguana's context.
