User Switching from The WordPress Admin Bar

Recently I have been working on a number of multisite installs of WordPress. The largest of these has been for a multisite install that is being used as an Intranet in a corporate environment. To help see the site from other users’ perspective I have been using the excellent User Switching plugin by John Blackbourn. [...]

One thing that I have been looking into is to have a multisite installation of WordPress where the main blog holds master content. This can be be published or broadcast to other sites within the network, particularly when a new site is setup. Therefore you can have network sites that use default content from a master site. I think the solution lies with switch_to_blog() and restore_current_blog() but I am still looking into this.
