Hi Kris,

I'm working on just such a thing for myself. 
I originally wrote a filmres playback engine that
was used at Pixar for Bugs Life, Tapehouse, and a few
other places. I'm writing a second generation 
version right now which is more like a combination
telecine/editor/compositor. It's akin to a mini
avid/inferno/commotion tool.

The system that we were originally specing out for this 
was an an Onyx2 IR with 4 FC loops which is reasonably pricey.
However, if you wanted to do it on budget, you might 
want to look at an Octane based system. I'm currently 
assembling a system to do just that. 

The low cost, DIY/Indie approach is quite affordable.
Octane: ~25k
1 TB (28 36gb drives): ~42k
4 FC enclosures: ~10k

The differences between the Octane and Onyx IR features
don't sound like they're relevant for what you're 
trying to accomplish.

I've got lots of numbers and they're lots of variations
dependending on all the constraints. Too many numbers!

This could be a Spirit colorspace issue. It you can afford the extra 
scanning time, I'd go with a true 14bit rgb scanner and scan at 
4k sampled down 2k 10log or higher.

confirm this?
