Multisite for intranet/extranet I'm currently developing a Drupal environment for a school project. I've already read a few books about Drupal, but still need to improve my skills when it comes to programming.

The project exists of developing a new intranet/extranet for existing content. Currently, the intranet/extranet exists of standard html files linked to eachother. The content on the intranet(intranet.example.com) is only available for users on the company network. However, some content needs to be available on the extranet (extranet.example.com).

I'd like to use one Drupal installation to manage all content, users... Is this possible by using a multisite configuration?
Multi-site is designed for a shared codebase with seperated content.
It is possible to share a few tables within all multi-sites without complications (e.g. users, roles, session) but espacially sharing  of content and content-types is not quite easy.

I would suggest Domain Access: http://drupal.org/project/domain


  The Domain Access project is a suite of modules that provide tools for running a group of affiliated sites from one Drupal installation and a single shared database. The module allows you to share users, content, and configurations across a group of sites
