Glad to be of help. Raidframe had been ported to FBSD 5.x, but it was
removed because kernel changes broke it, and no one volunteered to fix
it. I think gvinum replaced vinum in 5.3 for the same reason. I don't
use software raid, so I don't really know.
But NBSD 2.0 is very nice. A company that I do consulting for has just
chosen it as the OS for a new embedded product in their pipeline. I've
been toying with the idea of idea of web-enabling my toaster by hooking
up temperature sensors and a camera, so web surfers could make toast at
my house. I was going to use a 8051 chip and write the code, but maybe
I'll use NBSD on an embedded board. (Someday, I may want to add the
sprinkler system, pool pump,....)

This was meant as a humorous question because of certain Windows users'
not well-reasoned or -argued posts on this very topic in the last few
days.

Different tools for different jobs. Although, in the thread you
referenced, you said you were having major SMP problems with NBSD. I
hope you get those sorted. Those, I would think, are worse than any
network and vinum performance problems. In any event you may wish to
check back when 5.4 is released. (No release schedule yet.)
