You know, this is the information we can't seem to get.  We 
can see that the symbols appear in the binaries of things
like Acrobat reader, java RE, Mathematica, Picasa, Real Player.
Quake. Even OpenOffice.  And we get squeaks from the producers of
some of those that they can't build because these things are
missing from LSB.  But when you ask "what is it you're actually 
using them fror" there's never any real data coming back... 
I always enjoy operating without enough information :-)
