Connection between pages

Question

I have a documentlibrary and a few questions about childsite to childsite, parentsite to childsite & childsiteto parentsitestructure.

Consider a documentlibrary that's on the parentpage and is filled with documents. I want to display that same documentlibrary on the childpage with those same documents. How do I accomplish this? And when I have a documentlibrary on different childpages how can I display those on the parentpage?

Thanks in advance.

There could be many ways, however with some constraints, and even require development.

Simple scenarios:

1. Use CQWP (Content Query Web Part) is the most simple to use - it does however require Publishing Sites (or to activate Publishing infrastructure). This allows for rollup of content across the whole site collection, including targeting a particular list at some sub-site level.
2. Use DVWP (Data View Web Part) - many ways to achieve it, mostly via SPD, but have a look here http://social.msdn.microsoft.com/Forums/en-US/sharepointdevelopmentlegacy/thread/cb8717b9-21fb-4f86-9489-93f478ecaf44 for a step by step example, or here http://blog.concurrency.com/sharepoint/sharepoint-2010-cross-site-content-rollup-using-sharepoint-designer-2010-and-a-dataview-web-part/
3. Customize a Search Core Results web part with a particular scope - less for targeting one list, works across site collection, but requires certain know-how.

More complex (aka Programatic) - even requiring custom Web parts that rely on rollup/agregation techniques (start here http://www.codeguru.com/whitepapers/article.php/c16999/Building-a-Rollup-List-in-SharePoint.htm). Use any of the ways mentioned here (http://msdn.microsoft.com/en-us/library/ff649417.aspx) which rely on SPSiteDataQuery (what CQPW uses also), PortalSiteMapProvider or other technique

If you are sharing the same content between them why not simply create one site, and create multiple pages within that?
