    Now, THIS is an excellent idea. If the volumes there would be high
    enough, it could be what justifies the project. We have had customers
    wanting embedded solutions, and through this project, we could provide
    them something even better in the future.

    This is a good idea too. I've already decided to try to fit it onto a
    1/2 height, short PCI card (like the low-end 3ware cards) so that you
    can put the card into one of these compact cases.

    At this time, I'm not sure it's worth it to do anything other than PCI,
    AGP, and PCIE, however. Of course, if someone comes along with a large
    enough order, we'd be plenty willing to do whatever customization they want.

    Force of will isn't going to get this project done. Money is what
    matters here. <sigh> :)
