Poul-Henning,
Do you need 16 bits or can you get by with a 12 bit ADC?
Have you considered using an FPGA for signal processing? It seems you need a
fairly serious CPU to handle that much data.
You could use an FPGA, but the data rate isn't all that high. The
signal is fairly narrow band (<1 kHz, I should think). What you might
want to do is build a ADC/FPGA combo that provides a nice USB/Ethernet
interface for the sample stream which has been digital downconverted and
filtered. the FPGA takes care of the icky glue logic details and does
a bit of decimation.
