Both.
Kmud, the application, embeds KmudParts which are direct subclasses of 
KParts::Part.
Currently we have only one such KmudPart called mapper.
Mapper uses KParts::Plugin subclasses called CMapPluginBase to extend 
itself (such a plugin can provide views and tools, where tools are merged 
into a mapper toolbar and a tool menu)

Yes, think so, mappers actions are merged without problems.

IMHO that depends on the definition of "document".
A lesson or lesson collection could be seen as a document too.

Anyway, the document related API (openURL, etc) is introduced at 
KParts::ReadOnlyPart. If you subclass KParts::Part directly, you don't 
have to implement ULR related things.

Cheers,
Kevin
