<p>If I heard Oz and Esbee correctly, the whole of the viewer, with the exception of the proprietary libs they use (which I htink is the KDU jpeg2000 stuff and one or two media codecs at this point) go to LGPL. You can't mix LGPL and GPL deeply, as Adam's pointed out. I'm not enough of a LGPL wonk to know exactly where that takes things. I'd think the question is "does it change the dynamic on "derivative work" I know being LGPL means that one could link bits direclty into OpenSim legally. That's straightforward. What's less obvious is whether reading the LGPL code causes the same issues that<br>
reading GPL code causes. They did point out that they still insist on the contribution agreement, and that the contribution agreement was why they could shift licenses. <br>
