We have yet to see what form that will take. At the moment it's just defining internal things such that the materials are compatible - after that will come things like "How can those be exported, or moved between the applications?", which we don't have an answer for at the moment, sorry. That means exact workflows and what can and can't be done through those, will have to wait until development is further along. Long term, the situation you describe would be what we hope for, along with it making it possible/easier to bring over the Corona Material Library - but first things first, the internal stuff :)
