Hi,
my first use case is that I want to enhance the HomefolderManager to make it 
possible to select something else than a Folder to be created automatically. 
Right now I have forked a version of the HomefolderManager and just changed 
in the code. But I would like to have a more generic solution and I'll also 
commit it back to the trunk.
For that I want all classes implementing IContainer (and IContentType ?) and 
let the user select on in the configuration dialog of the HomefolderManager.
More use caess probably show up in my project later, but nothing fixed at this 
time.

Thanks,

Florian
