Oeps, seems like I've been a bit to fast.
and I consider if we should use a common local repository - for instance over a network share.
You're talking about a common local repository. I agree with Christian, this could slow down things a lot. And it makes it more difficult to experiment (though you always can changing the settings.xml you use.) I also strongly recommend to keep the LOCAL repository, really local, meaning on the developers workstation.
