You can still choose which content directories to use, but the files go in DataCloudproductID and can't be moved from that location (but you can safely move the DataCloudProductID folder to a different content directory, something that wasn't true without tidying up in earlier versions). What you can do is create a special new "shortcut" file that points to the user-facing files (the ones you see in the content panes) and move those around as you see fit. Files for content that is already available, or that is released through DIM as well as Connect, are no longer encrypted in the latest beta - only Connect-only content will be encrypted.

Going back to an earlier post, Rob Whisenant did post in one of the Daz forum threads to explicitly state that Carrara support for Genesis 3 is being worked on (or perhaps that Dual Quaternion rigging was being worked on, so that Genesis 3 could follow) and as I recall that Connect support is also planned.
