This is true. On the other hand, using a literal file:// or http:// or
sftp:// resource means that my existing tools, which will let me copy,
delete, commit (with nautilus plugins), rename the branch will be

branch = Branch(url, find_root=False)
branch = None
branch = GitBranch(url)
I've written more such tools now than I can remember, and its really
quite easy : you end up with a factory that goes:
tree = VCS.tree(url)

It is an appropriate use of std66, the real question is - are we
creating a sufficiently different protocol that its a win to go down
that path. At the moment I'm with Aaron - I think we should use file://,
http://, and sftp:// urls : we aren't changing the protocol for
accessing the resource enough to make the loss of interoperation a win.
