Getting a lightweight one *may* be cheaper, depending on how much history is needed to reconstruct file versions. > To me, this sounds like it might be talking about a "lightweight > checkout", as I believe a checkout is a complete copy of the branch, > and network access is only required for commits or updates.

A checkout --lightweight over the net is currently not a good thing to do. When the smart server is released, that will be about the same performance as traditional client-server vcs's like CVS or SVN. > > My central dislike of bzr is bugs like: > > http://bugs.debian.org/380412 > https://launchpad.net/products/bzr/+bug/54253 > > ...which unfortunately makes it unusable for some of my applications. Are you doing conversions from SVN? Current bzr uses 20MB of ram to do a native branch operation in similar circumstances. (bug report gets fixed, new at 11 :)). 0.9RC1 is out, and 0.9 will be out Monday/Tuesdau. As soon as that lands in debian the bug should be closed.
