great thread on pelican about an oil-fed ims:
Who has done an IMS change (New Oil Fed Design Idea) - Pelican Parts Technical BBS
started about a year ago. now Raby has one in development. parallel evolution?
from what i can see, feelyx taps the block and runs a line internal to the bellhousing. the raby solution uses an external oil line (from a sandwich plate on the filter?) that passes through the bellhousing. both use an exposed bearing and a modified cover plate with an oil fitting.
one of the things that feelyx's design does that i'm uncertain the raby one does is move the bearing further inboard in an effort to reduce radial torque on the bearing (presumably one of the causes of failure, along with insufficient/failed lubrication).
