Cool idea on the flyer stuff. For the folks in Europe this Flyer system as great. I used two of these daily until 2005/2006. The systems wre retired simply becuase I could no longer relaibly source parts (Amiga 4000's) and the fact that the Tricaster and a VT5 and good laptop are easily replaceable and more versatile.
IT would be cool to see the flyer and Toaster 4000 integrated into 1 card using and FPGA solution. You could probably do the whole thing in one chip I reckon.
