This post to advise that has been recently released the beta version of Media Browser 3 Server. Since this version has been developed using mono is able to run on every system having mono > 3.x installed (I have tested it on Trimslice).
If you want to give a try you can find it here: http://mediabrowser3.com/community/index.php?/topic/3634-mono-server-linux-os-x/
MediaBrowser 3 Server is like Plex (but better). It allow to stream media contents to clients with full support of backdrops and themes like XBMC (but better).
