There are things that you can build with a dozen $30 rtlsdr dongles that would be export controlled.
The bar is pretty low these days. It reminds me of the time Phil Zimmermans PGP was considered a munition for USA export purposes
The KrakenSDR is certainly toeing the line.
I think that it should be possible to distribute clock lines to at least a 16 channel engine using Tayloe polyphase detectors, which have really good noise characteristics, image rejection, and incredible dynamic range, they also make efficient use of the received signal. One 8 phase clock to feed it all, and coherent downconversion is guaranteed.
Parts cost would be $100 or less via Digikey.
