If you're using ZPatterns anyway, you might like to look at PlugIns. The 
idea with PlugIns is that a PlugIn manager delegates the handling of 
objects it contains to its various PlugIns. Typically, a PlugIn will 
claim objects based on the object's meta-type.
PlugIns appear in the user-interface as separate tabs. See the 
Customizers and Data Plug-ins tabs in a Folder w/ Customizer Support 
instance for an example.
