Network Sidebar Widgets

In the multisite context, creating widgets that are used throughout all of the sites in a network can be difficult and painstaking (at best).
This plugin gives network administrators the ability to create “fallback widgets” that will be used as the default unless over-ridden by individual sites.

How the plugin works

• When a widget is created on the “main site” (e.g. site ID 1) the output is cached.
• When a sites other than the “main site” (e.g. site ID != 1) call a sidebar that doesn’t have any active widgets, the cached output from the main site will be used.
• The plugin may not (read as “probably won’t”) work with highly dynamic widgets
• This is the initial release, so please try it out before you use it in a live site.
