Almost certainly the case right now.

Not sure--somebody should take some measurements.
I'm increasingly liking the approach where you "demarc" at the digital
output of the ADC that I suggested
earlier where you terminate in something like a LPC-FMC connector or
something equally
convenient, which allows you to adapt to various "getting bits to the
host" approaches. Including:
o 1GiGe
o USB-2.0
o USB-3.0
o PCIe
But maybe that's the road to *more* expensive, not less (although cost
is only ONE of the factors
of a project like this).
