I think original cards and let's call em "replicas", like replicas of old cars, can exist in the same universe parallel with no harm to each other. A discussion about money isn't going anywhere I fear, you simply have different points of view on this matter.
In my opinion it's better concentrating on the technical work that's done here in this project. It's really a very impressive thing to construct such a card, respect Anthony - awesome work here
Looks to me like a new interpretation of a 6000 rather than a remake. I like the idea of this card as an additional Glide Accelerator addon card like a Voodoo2 with VGA Loop Connection.
Just a thought - have you considered designing it as a PCI Express x1 card? Is that possible with another bridge chip? Then you eliminate the bandwith bottleneck legacy PCI and there are plenty Platforms out there you could use the card with the latest XP32 drivers (socket 754/939/AM2/AM3, 775 11xx and so on). And some of them can also be used with good old Win9x
Somehow I 'd really like to see a PCIe Voodoo
