+* The Glorious what.cd¹ Resolver
+
+  ¹: At the time of writing, what.cd didn’t even exist anymore
+
+** Idea
+   
+   Stream your music (or media) from a private tracker transparently.
+   “Spotify for torrents”
+
+** Technical
+
+   You need to have a seedbox, which runs a server program.
+   The server manages queries, downloads torrents and requested files, and
+   provides http streams to the downloaded files (while caching them for
+   seeding).
+
+   Clients then use the API to search for music (e.g. query for artists or
+   tracks) and get back the promise of a stream to the resolved file (a bit how
+   resolvers in the Tomahawk Player work)
+
+*** The Server
+
+**** Resolving queries
+
+     ~resolve :: Query -> IO Identifiers~
+
+     A query is a search input for content (could be an artist or a movie name
+     or something)
+
+     There have to be multiple providers, depending on the site used
+     (e.g. one for Gazelle trackers, one for Piratebay) and some intermediate
+     structure (e.g. for going through Musicbrainz first).
+
+     Output is a unique identifier for a fetchable resource; this could be a
+     link to a torrent combined with a file/directory in said torrent.
+
+**** Fetching Identifiers
+
+     ~fetch :: Identifier -> IO (Promise Stream)~
+
+     Takes an Identifier (which should provide all information on how to grab
+     the media file and returns a stream to the media file once it’s ready.
+     
+     For torrents, this probably consists of telling the torrent
+     library/application to fetch a certain torrent and start downloading the
+     required files in it. The torrent fetcher would also need to do seeding and
+     space management, since one usually has to keep a ratio and hard drive
+     space is not unlimited.
