Catch user virtual file system request

[Riccardo Tribbia <ricky tribbia gmail com>]

Do you know any method to catch user request between local file system and virtual file system into a python nautilus plugin?

Examples:�

1. if a user makes a "Create document" or "Create Folder" request (through right mouse button) can I catch this request and stop it, but retrieve relative path?
   (es, in webdav folder: dav://---------.com/MyFolder/) ?�
2. if a user drag and drop a folder or a file in / from a virtual file system (es webdav) can I stop this request and catch path from an to of "Move to" request?
3. if a user copy and paste a folder or a file in / from�a virtual file system (es webdav) can I stop this request and catch path from an to of "Move to" request?

Thanks a lot!
