I'm a fan of the idea and design, but I'm curious how well it works for non Apple users. Is there a web interface planned? I've been wanting something like this for a while now. Syncing with existing calendar apps would be cool too, but I care a bit less about that, and maybe a bit more about some form of self-hosting the data.
