Yes, the filemanager-like API is pretty central in OGo. Eg another 
important aspect is that filemanagers can return datasources for 
folders, which is a must-have for "filesystems" like IMAP4 or database 
tables (potentially containing hundreds of thousands of records).

Anyway, writing something like this for a desktop application is quite a 
major task (lets call it Zzz ;-).

I know we disagree here, but NSFileManager is not a suitable API for a 
GWorkspace in the VFS environment because it is a synchronous API. Now 
fetch a WebDAV folder on the other side of the ocean and see your kernel 
being blocked (usual in MacOSX ;-)
