Looking at our support database, we have had one user earlier this year report to us that using the XBMC device profile in Mezzmo with their Pivos AIOS HD Media Center worked great. He did not say whether artwork was displayed or not on the media center though, so I cannot help you there (...Mezzmo will of course deliver artwork to the media center if it requests it, just like it does for any DLNA/UPnP device).
