OK, so if I can see some interface function (like SOCKET-RECEIVE) in svn trunk, I'll start to learn them and write/test some backend code as your design and commit to you, and I'll start to make my package depends on usocket to get networking portability.
I'm sorry you didn't see anything yet. The commits you've seen until today were about me cleaning up loose ends and implementing ideas floating in my head for months (as I could not commit them - my hd had crashed). I need to get rid of that mental state to be able to start the UDP work, so, that's why. I hope to be able to do some interface definition work today.
If you have any questions, or need some information to be able to proceed, don't hesitate to say so!
bye,
Erik.
