I'm giving Pedro's technoFix DOF another look.
From Pedro's site, describing his product: "
[O]ur oil supply to the DOF uses oil which has passed through the filter and then through the cooler, before it goes onto the IMS bearing. ... This oil feed is supplied by the factory, so there is no drilling or tapping on the engine, simply screwing on a (supplied) adapter."

If it's true that cool, filtered oil lubricates the bearing then Pedro's technoFIX is equivalent to LN's Solution for less than half the cost. The price for the technoFIX is $800, which doesn't include the bearing, $50 for single row or $100 for double. (At this point I don't know which one my new engine has. I'll need a bearing extractor and the doohickeys to lock the cams and remove the timing chain tensioners before I can find out.)
I emailed Pedro and asked for a better description and/or photo of the aforementioned screw-on adapter for the oil feed. The other end of the oil line is connected to the flange, like LN's Solution.
