Well, 18 months ago ESA were getting 50Mb optically between satellites 

  http://www.esa.int/export/esaCP/ESASGBZ84UC_Improving_0.html

since that is 

1) a Moore generation ago :-) (though I think development times are
   longer in space technology)
2) public information

I expect that the people on the "dark side" who do this can indeed get
an awful lot of bandwidth...

(ISTR Chaisson in "Hubble Wars" mentioning that they were borrowing
the 10Mb link to space that the NSA folks had back in 1991).
