However, i have yet to figure out how to obtain the children for each section/chapter. Rather than taking a guess with trial and error and searching through more Sword frontends' source code, i would prefer to have a _full_ understanding on how Sword handles GenBooks and how frontends can make use of those methods.

Am i right to assume that i have to use SWModule::setKey() to set the current key to one of the root sections and then re-cast SWModule::getKey() to a TreeKey and iterate through that? Or is another method required?
You might want to look into the documentation on
http://www.crosswire.org/~ghellings/1_6_0classdocs/ for version 1.6.0
of the engine. Particularly look under TreeKey::firstChild() and
