I do understand your concern, and I think it would be good to support
your use case as best as we can. However, I think developers like us are
in the minority, versus people who will be using bzr in an environment
that they don't have access to /usr/lib but want to install a newer
version of a plugin.

One argument might be to have a default site location for plugins,
rather than /usr/lib/python2.4/site-packages/bzrlib/plugins/*

And then it could be a 3-tier. Load from bzrlib/plugins, then from user,
then from site-wide.

At the moment, though we only have 2 locations, so bzrlib/plugins should
be underneath user plugins. Otherwise users have no way to override site
installed plugins.
