Get it to respect scopes?

[tobiasgr]

Hi
I am currently using this gem to list pages on the website in a hierarchy and it works great. I would also like to use it to manage multiple websites from the same admin. But I would need this to work with scopes, since I would need to make a scope per website to manage the sites and structures for each site.
Is this possible? I have a hard time grasping how I would make it work...
