Yes, unless you're in the habit of publishing or otherwise sharing your working
copy (the thing use your editor on) ;)

For almost everyone this is local to a particular machine.  If you have a tree
on a network share, and that tree is accessed from multiple machines, then there
may be an issue if someone on one machine upgrades the tree to a format that's
too new for another machine's bzr, but that's pretty rare.  After all, part of
the point of version control (and particularly distributed version control) is
to enable multiple concurrent copies of one thing, because it's generally easier
to manage (less treading on toes, etc).
