Flickr needs dynamic albums of your network's photos

So I have this network of friends with pictures that I really like; with all of the social design of Flickr, why can't I make smart sets of photos that are mine, as well as my friends/family's? Why can't I search for "kevin" and create an album of pictures my parents, my brother, and I all tagged that have me in it? Why can't I take a picture that my friend gave me rights to, and add it to one of my collections?

I'm sure other services are offering this - even shutterfly has the option to take your friends photo albums and add them to your collections. Does Flickr offer this and I'm missing it?
