There is! netatalk on linux is the package you need for that, and it's still built in to BSD, I believe. now weather that package still speaks the older versions of the protocol, who can say. Interestingly, a challenge you would have with this because this emulator is web based, your networking options would be fairly limited, even if you could emulate netatalk, the browser's security features would preclude you accessing hosts than the server it's on, it's the same reason Fabrice Bellard didn't add networking to his jslinux project.

netatalk provides macintosh fileshare hosting services on unix/linux. It has nothing to do with this use case.
