With regards to the PCIe interface, were you looking more at just getting a PHY transceiver and putting the MAC and other layers in the FPGA, or were you more interested in having a PCIe bridge chip that handles all of that for you?I know Philips and TI have PCIe transceivers which work with Xilinx and Altera IP for the MAC layer, but what I really found interesting was a PCIe bridge chip from PLX technologies. It's a relatively hefty BGA, but if you can place it properly the chip could really be a huge help. No NDA's are required and the information can be found here. http://www.plxtech.com/products/expresslane/pex8311.asp Do you have a place where you are hosting your thoughts/ideas on the subject, or just some e-mail threads?

It's a very nice chip, but it appears to be very expensive at $38... =( TI's costs $7, which is quite affordable. I'm not sure how to address the IP core issue yet. The Open Graphics project will have to deal with it sooner or later, but I hope we will coordinate efforts. I told them what I had discovered so far, but I'll have to see how that discussion turns out before I can say if it'll be any help. If you know anything about the problems I need to solve, I'd love to hear about it. :) I don't have a site yet since so far I have little but a fuzzy picture of what I want to do. I'm still trying to find out if it is actually even doable. The hardware seems possible, even for $100 if I use a slightly cheaper ADC than I'd like, but to then process this massive amount of data I'm rather unsure about. I emailed the FFTW project, since I figure they're the experts, but as of yet I've seen no reply. Might be there's no one checking emails at weekends... Once I have gathered a little more real data and can come up with a workable plan I'll probably set up a site of some sort. Maybe a simple blog.
