It has now, but it's the first time I've heard of it.

In fact, I never asked VERITAS. I only modelled Vinum on VxVM,
anyway; there are big differences.
In any case, there was one IP issue at the very beginning: I developed
the RAID-5 functionality under contract with Cybernet Inc., and part
of that agreement was that I would not release it until 18 months
after it became functional. That time has long passed, and RAID-5 has
of course been released. There have never been any conflicts arising
from IP issues, neither with Cybernet, VERITAS, myself or anybody

The original intention was to modify Vinum to work with GEOM. Lukas
did the work, and he chose to rewrite significant parts of it, and
also to rename it. I disagreed with both of these decisions (see the
problems they've caused, like what's being discussed here), but he's
the man, and he gets to call the shots.
