Update: we got hit with the $475 'processing fee' as well (NASA/MSFC
for their 'governmental use' agreement) but no other fees. Restrictions
include no redistribution of software incorporating LZW functionality,
which I read to mean we can't send homegrown IDL code with
READ_GIF/WRITE_GIF functionality to our data users. Debating whether or
not its worth it... the 6/03 expiration info is helpful...
