Thanks for clarifying this. I was hoping the expiration of the LZW patent meant I could add LZW compression to the iostreams library. To you have more info on which other countries have issued patents on this algorithm which have yet to expire?
... Although this patent has expired in the United States, patent searches by the FSF show that worldwide patents exist until 2006. If you must have a patent free version of the library, please look into libungif as a suitable replacement.
So perhaps you could ask them...

Thanks. Maybe I can add the code now, but with BOOST_STATIC_ASSERT(__YEAR__ >= 2006); ;-) Jonathan
