It has an API, but the plugins are not interface based (so interface 
requirements don't need to be part of the plugin system).

PEP 376 is *very* promising for this part - well at least if the PLUGINS 
stuff becomes part of PEP 376, it doesn't seem to be mentioned at all at 
the moment. Based on what you and tarek are saying it *sounds* good 
though... (Metadata for packages to declare that they provide plugins 
for another package and an API for frameworks to discover installed 
plugins.)
