sorry if this is in the wrong section, I couldn't decide wether this belongs here or under data compression.
Anyways: a few months ago, I released packJPG under the GPL v3. However, some people pointed out that this will make packJPG incompatible with other projects such as 7-Zip. Because of this I've been thinking about a re-release under a different license, or maybe dual-licensing. Being no expert at all in licensing myself, I'll just ask you .
So, what do you think, what would be a good license to release packJPG under? I could use some help.
