Pretty good so far
Starts up and does what it shows in the screenshot: shares your iTunes media without needing to muck about adding folders or processing files. However, a couple of caveats. First of all, album covers don’t seem to be coming through. Not sure if it’s completely unsupported or only by my client. Second, it only seems to support Photos and not iPhoto/Aperture. Of course Photos is the future, but it’s not ready to replace iPhoto yet. Other media servers supporting iTunes DO still support iPhoto.
