I think that the key to long-term archival storage is that in the future, all storage will be live storage. There won't be dark rooms full of degrading tapes; as storage becomes cheaper and denser there's less need to actually take data offline for archive. If the data's online, it can be maintained more easily and erasure-coding setups ensure that if physical storage units die you can just plug in a new one and go on. Also, data can be stored in a distributed fashion, so you don't have to worry so much about something like a fire in the warehouse.

ClearCase appears to let you mechanize local management hierarchy and policy. If your manager -- and only your manager -- is authorized to commit code changes to the shipping base of code, ClearCase will let you describe that workflow and enforce it for you. For large organizations with a management fetish, this too is a "feature".

Of course, Git also supports this feature. In fact, if you're using Git in the normal distributed fashion where everyone pushes to their own public repositories and pulls from the master, it's the default behavior.

I mean, who has more of a management fetish than Linus? Of course, his idea of management is not horribly dysfunctional like you're suggesting...

Apparently you haven't been introduced to the 'git submodule' command? You can add modules (recursively) at any point in your source hierarchy. Such modules are entirely independent git repositories; all that's tracked in your base repo is the version of the checked-out modules.

Git's SVN gateway is principally useful for migrating projects hosted on subversion to git. The simple fact is that git's change history cannot accurately be represented in subversion, so transformations back and forth between the systems are lossy and painful.

Right, because geography is *such* an important factor in determining what is important in terms of a primary education.

Why should curricula vary based upon our arbitrary state and district lines? Why should it be the case that if you grow up in the wrong place, your education sucks because the local yokels think that the earth is 6000 years old and the Rapture is impending?

If the Department of Education has problems, let's talk about fixing those problems. Throwing the whole thing out in favor of a strictly local approach just means that in less educated areas of the country the dumb just get dumber and the smart kids get screwed.
