Done! Not that I am really using it (yet?), but I'd love to play with it, especially the forum feature (reminds me of usenet clients, which I never really got to use because that was before my time) - so feel free to "add me" if you're a "casual" yourself, or even if you're super serious about it, but don't mind playful old me.
(It's not just file sharing, though: it aims to address your entire encrypted p2p communication needs.)
