You can get notifications by mail but you can't reply by mail yet, it's a good idea though and we may add it in the future. Also, if you know rails you could actually help us add it :)
Yeah. thing is, I've not seen a good integration between forms and email. I bet the hard part isn't implementing; it's figuring out what a good implementation is. Ultimately, you'd want the email interface to look like an email list, and the web form to look like a web form, but you'd want the content on both, and I'm not sure what the best way to do that is.
