I've never heard of Fluorine, but it looks interesting.
If you really need to work with completely detached serialized objects then you should have a look into the ObjectNetworkAttacher.cs file that can be found in the src/Helper directory of your OpenAccess installation.
This class provides the functionality to logically reattach such a disconnected instance in an object scope.
I hope the code is self-explaining enough.
