Hi, I'm the author of libnui which has been discussed here two days ago. (i saw this list archive in the referer stats for libnui.net and was curious ;-) ). Some people seemed interested in nui but had concerns about it's licensing. I summarized our choice of license in this wiki page: http://redmine.libnui.net/wiki/libnui/Licensing . We're not particularly happy with the GPL but we found no real other option that permitted to fulfill our requirements listed on the page. As others have noted C++ is a very ugly language and recreating a useable object model have been quite a chore. I'm curious about how we could change nui to make it more friendly to other languages such as smalltalk, knowing that C++ has always been a tad harder to interoperate than, for example, C. Thanks in advance, Sébastien
