Moving convos between projects... Anyone else do this?

I have dozens of projects on the go, often with overlap - projects to create APIs, projects that use those APIs.... They aren't mature enough to say the API is yet final - the first implementation tests the API and there are questions over whether the API needs changing or the app using it does... I have tried various ways of facilitating the cross communication without loading up loads of irrelevant cruft in the others project... Currently I am experimenting with teleporting/jaunting a chat between projects, it lives in a project creates artifacts... Then is moved to another project (with its artifacts) with that other projects knowledge base to call on I then get it to extend the artifacts it is carrying with it... Has anyone else tried something like this?
