Sadly, it has been made abundantly clear to me and my colleagues that 
merely because something is published in the open literature does not 
make it export-control free.  We are specifically cautioned that 
pointing someone to a set of papers in a particular area falls in the 
category of "providing technical assistance with the design of defense 
articles", for which an export license is needed.

If you come at it with very clean hands.. purely research into 
fundamental scientific principles.. then you are pretty safe, but as 
soon as you start talking about design and build specifics, or 
identifying and ranking alternatives, then you're in dangerous 
territory.  (speaking here ONLY of things that go into space, since 
unless specifically exempted, pretty much anything in space is a 
"defense article")
