Let me take this opportunity to extend you a firm virtual hand shake with
a Thank You for that offer. I caught your initial offer, and was more
than pleased to see it. As I am near to accepting that offer. But I'm in
the middle of a build and image rollout for our hardware upgrade. This is
good news for me. As when I'm finished, and all the dust lands. I'll have
a surplus of hardware to re-purpose. It is my intent to use it for some
serious OI development. My background is BSD. So any help you would be
willing to provide to shorten the trajectory, would be GREATLY appreciated.

Thanks again. Be talking to you soon. ;-)
