People, I think we should make it clear that neither Vinum nor
RAIDFrame are perfect.  We shouldn't chuck either out at the moment,
and it would be really nice, as phk suggests, to have people working
on both.  Both are rather old now, but they contain good ideas.  It
would certainly be an excellent idea to improve them both.  We
shouldn't be trying to compare their relative merits at the moment.
Wait until they regain their strength.

I'll answer phk's suggestions separately.
