My understanding is that with git it's possible to "graft" one tree onto 
another, so that most people only have to check out recent history, and 
can check out a separate ancient history.  This has at least been proposed 
in the context of the net-im/zephyr upstream, where development happened 
concurrently in multiple trees (in different VCSes) for a period of time 
maybe ten years ago.  Current development is all consolidated in a single 
subversion tree, and the proposal was to convert that repository now to 
have something to work with, and worry about getting the ancient history 
right at a later time.
