Umbraco multi-site site with shared content
There was a nice session this year at CountryWide's Umbraco CodeGarden which might be worth watching as it discussed a group in the housing market that has about "40+ different high traffic sites from one Umbraco install" but shared content between many of sites in the group. You can watch the video here:
http://stream.umbraco.org/video/9921509/40-different-high-traffic-sites-from-a
I would recommend watching the entire video, but if you can't go 25 minutes to watch this discussion thread. They have a common content node (+ children).

I would recommend that you stick to existing websites and not create a repository website. This makes it easier, I think, to define canonical URLs for documents if they are to appear across multiple websites. Also makes it clearer from a content editor's point of view. To reach content from another site, I would use code like this (considering Umbraco 7+ here):
// Root nodes
var root = Umbraco.TypedContentAtRoot().First();
var site = Model.Content.AncestorOrSelf("Site");
var lang = Model.Content.AncestorOrSelf("LanguageHome");
var allOtherWebsites = root.Children.Where(x => x.Id != site.Id);
var newsFromAllOtherWebsites = allOtherWebsites.Descendants("News").Where(x => x.Parent.Name.ToLowerInvariant() == lang.Name.ToLowerInvariant());
// Do things with news...
I also added something for multilingual installation, you can just uninstall them if you don't need it.
Hope this helps!
