As I mentioned in an earlier post, I've been quite busy at home, and expect to be for a few days to come, so I apologize both for being so late posting, and for not posting my own API plans. Your blog post has given me quite a bit to think about, thank you! Do you mind if I work up an API similar to yours? I'm planning on using a different license (not LGPL), which is why I ask.
