i know that they use labview and national instruments for some components, but my comment was more along the lines of "if they have some large dependence on labview and ni hardware, then [it would be very surprising...]".

however, it does seem they have used it a lot, at least in the past. they have a site license (which is uncommon except for universities) and what appears to be a large internal component written in labview.

if someone is heavily using ni hardware and software, then there are really not many alternatives at all.
