Vista - library in vista

Is there anyway to imitate the "Library" functionality in Explorer from Beta
1/pre-Beta 2 builds of Vista. I created all the Virtual Folders analogous
to the ones in the Library but I can't find a way to display certain ones
from certain shell folders.

I guess a way to do this would be by having certain "Favorite Links" for
certain folders, but I don't think this is possible. Is it possible,
through drag-and-drop, registry hacking, or shell scripting/programming?

Thanks, because this was a really useful feature and it sucks that Microsoft
removed it!
