Detailed Plan
The idea of an open window into the data sphere opens up bucketloads of utility. From a static window that your wallet visitors can interact with, to displaying the data stream of sensors in the field. Any number of possibilities arise once the mechanism arrives.
This idea is in the ecosystem challenge because it represents a means for future development. Data and services could flow through NFT and they could even become part of a new interface for Art and data consumption. Smart Contracts enable subscription terms, but selling just a chat window would be bad ass.
These could have a login so only real owner can use it, but they could go wallet to wallet, or within a group (when group ownership comes into play).
