There are two forms of checkout: a normal checkout which contains the complete history of the branch, and a lightweight checkout, which just has a pointer back to the original location of the history. In both cases, a "bzr commit" invocation will commit changes to the remote location. In general, you only want to use a lightweight checkout when there is a fast reliably connection to the branch (e.g. if it is on the local file system, or local network). Aaron would be talking about a normal (heavyweight) checkout here. With a heavyweight checkout, you can do pretty much anything without access to the branch. In contrast, almost all operations on a lightweight checkout need access to the branch. James.
