well, in git the commit-ids also represent the state of the whole tree
like in svn.

without rechecking, from what i remember reading there are local
revision ids which are sequential, but also hashes (either for the
commit or the tree) which are global like in git.

it makes sense for any dcvs. if i am interested in the commit-id then
chances are that i already have a local clone of the repo in which case
i can use the global id locally. (this becomes significant for bzr which
has both)
