Ok, I'll bite.  What you're suggesting is that instead of developing 
just a graphics card, I should develop a card populated with a bunch of 
FPGA's that's reprogrammable.  Putting aside the logic design tool issue 
(which may be difficult), what you'd get is a very expensive 
reprogrammable card with some RAM and some video output hardware.

How much would you pay for THIS card?  $2000?

Now, the thing is, this card is SO generic that Tech Source would have 
very little value-add.  Say we populate it with a bunch of Spartan 3 
400's... well, you'd download Xilinx's WebPack, code up your design in 
Verilog (Do you want to learn chip design???  It's not like programming 
in C!!!), and then use our open source utility to upload your code.

GREAT... until some other company comes along and clones it, which would 
be WAY too easy to do.  Now, for the users of this sort of product, it's 
a fine thing.  But it becomes a pointless investment for Tech Source, 
which is where I work and who pays me to work on this stuff, which they 
wouldn't do if it's not worth it.
