Just got my first project at Sun released, for early access anyway. (Ok, my actual first piece of code was a bug fix, but it was literally one line, so that hardly counts.) It's a bit of an obscure one, it lets you use VMware's virtual desktop infrastructure from Sun Ray thin clients. So what this means is, (apart from Sun Rays being awesome) you can use your virtual Windows PC from your Sun Ray. So you get all the smart card, host desking, and security for free.
