REST constraints an DCI

I'm searching the web to understand the impact of different ideas on DCI.
Here's one:

    What would be the impact of requiring the relationship between role and roleplayer to conform to (an adaption of) the REST constraints?

1. Is there a relationship between REST and DCI? (A role is not an object, but an interaction is identified by the context ID)
2. Is the REST cacheable property related to props?
3. What about code on demand and role scripts? 
4. Is Client-side scripting = Role scripts?
