integrating a new media type is a big job (just ask Thom, or look up the MAME effort)
But there's no reason why you can't use KDE desktop and things like the included bt client to do that outside of LMCE. bt doesn't really lend itself to meaningful integration as you have to search for the torrent in the first place, in which case you might as well use a dedicated client to download it. Torrents aren't the type of thing you are going to pause, fastforward/rewind, send from one MD to another, or trigger lighting or climate systems on, or by for that matter!
