website for multiple wordpress

Hello Everyone,

Okay, I’ve tried to search the extend and the codex but found nothing to do what I want to do, so I will ask here if someone knows how to do the following:

I have 3 wordpress blogs installed on three different databases and directories. I would like to create a page as a home page for the site and include in it some information from the three blogs such as latest articles, some custom fields maybe.. etc..

And I would like this page to have a similar theme.

Any ideas?
