 Prediction: just as DVCS killed off pre-DVCS practically overnight, the thing that will quickly kill off DVCS is a new type of VCS where you can trivially combine/separate repos and sections of repos as needed. You can assign, at the repo level, sub-repos to include in this one, get an atomic commit hash for the state of the whole thing, and where my VCS client doesn't need to actually download every linked repo, but where tools are available to act like I have.
 
-In a sense, we already have all of these features, in folders. You can combine and separate them, you can make a local folder mimic a folder on a remote system, and access its content without needing to download it all ahead of time. They just don't have any VCS features baked in. We've got {filesystems, network filesystems, and VCS}, and each of the three has some features the others would like.
