Again, someone may litigate Boost and part of it may be invalidated, for 
example, a judge may rule that the phrasing isn't clear. That would mean the 
license would have to be tweaked. It also is possible that Boost may not comply 
with the law in Country X, and that would need a tweak. With copyright 
assignment, these will be minor problems rather than major ones.

Also note that changing the license does not invalidate the previous license 
applying to previous versions of the code. Those remain intact. Digital Mars 
cannot retroactively take away Boost from the existing code. Any revised license 
would only apply to future works derived from the relicensed code.
