It sounds like they will be treating Embarc members like resale trust owners. Since Embarc came into the Diamond fold it has been the only one that allowed resale owners to use II. All other trusts resales were restricted and not allowed to exchange through II.
Embarc owners who do not have Extraordinary Escapes, Monarch Collection accounts, and European Collection resale accounts all have access to II.
Within the last two years, Diamond began providing II exchanges for resale accounts in the US and Hawaii Collections. The procedure is not convenient but it can be done. The owner of the resale account must have an individual II account. They must call DRI customer service to make the II reservation. And DRI will not make a "deposit first" transaction.
This is from the DRI attorney.

"Finally, if a purchaser on the secondary market does not want to purchase additional points from Diamond, but wishes to stay in properties outside of the 49 Collection resorts, that purchaser may become an Interval International ('II') member and exchange into their more than 3,000 destinations."
