I'm setting it up now, was close to give up when it continuously refused to work after setting up an account. Turns out the passwords randomly generated by Firefox is a bit too hardcore for it, I changed to something with fewer special characters and now all is good. :)
Edit: It worked for setting up the interface and my profile, but I still cannot sign in from within it. Seems like a promising project though.
Edit edit: Moved it from a subdomain to a normal folder, now I can sign in, but it still acts a little broken, and doesn't federate. Oh well, I'll see if I'll tinker more later.
