Flyback with LAN transformers

Ok, most of us have used LAN tranformers for power transfers. However, their datasheets are skimpy at best and usually contain no information about the core. Of course it won't contain any regular air gap and you cannot easily install one later because it's all potted up.

So, did anyone use these for a flyback design yet? Low power, something well under 100mW.
