I've never tought to go to a patent site to get the compression algo ..

I live in belgium, there is no ( yet ? ) software patent here. So If the patent forbids me to decompress jpeg lite, I'll release this part of the code as geographically limited GPL, as Alan Cox says : > Or live outside the United States of America and include a geographical > restriction in the GPL license for that code (explicitly permitted by > the > GPL for such cases). But i'll ask one of my friend to be sure i need to do it.
