William Carrel used to maintain a set of patches for RAIDframe on 4.x, 
were they ever committed? No? Why not?

WRT lack of interest in RF. First, the 5.0 patches were horrible. That 
code was a mess to work with. Second, inertia. Most people with simple 
needs like mirroring and/or simple stripes were happy with good old 
ccd(4). Those who needed a full volume manager (which neither ccd nor RF 
claim to be) used vinum. People with VxVM experience feel at home with 
it. Unfortunately, vinum has its own set of issues as well.

It's probably easier to write a set of GEOM classes from scratch than 
trying to shoehorn RF into GEOM.
