PCBExpress for the boards, by qty 20 things get cheap quickly.  7 mil
spacing is fine for this app.  I'm not sure if I'd actually use a Virtex,
there are other cheaper alternatives that would work here.

Never doubt the power of free samples for misc parts.  Maxim is your
friend.  :)

There's only one key benefit to solid state disk over system RAM:
stability.  A dedicated device with dedicated firmware is in theory more
immune to any action that will bring the host system down, and should
retain its contents through just about anything.  This is the reason
they're still used for logging/journaling devices.

$50 would be tough to hit in low qty.  $75-100 would definitely be doable.
XCV50E-6CS144C is $33 in qty 1, drops to $20 quickly.  LVDS I/O, mmm.

Want an async multi-megabit RS232 state machine that fits in half of a
9572?  :)
