 h2. Description 

 A bit brainstormed for the moment ;) 

 * Designed for LAN usage (full trusted peers) 
 * Efficient (very low cpu usage) 
 * Distributed download (multi peer downloading and no central server) 
 ** Quicker seed first. The speed of a peer is an average over a period of time say 5 min. A speed of a peer can be unknown. If a downloading is too slow (like three time slower than the best known peer) then it can switch from a quicker free seed. 
 ** Rarest parts first. 
 ** A part can be resumed from any peer. 
 ** Fixed part size (2^24 B = 16 MB) hashed with SHA-1. Used to control the integrity of parts and to identify a file. A file is identified by the concatenation of all the SHA1 of all its parts. If the SHA-1 of a part does not match with the given SHA-1 then it will be re-downloaded entirely. 
 ** Recursive folder downloading 
 * There is a general chat 
 * Multicast UDP for services discovering (maybe UPNP) 
 * MDI GUI with GTK2HS 
 ** A panel to view the current peers 
 ** A window to view the current downloads (leechage) and one for the current uploads (seedage) 
 ** A window for the chat 
 ** A window for searching 
 ** Some windows for each file browsing 
 ** A modal window for the settings 
 *** The shared folders 
 *** The incoming folder 
 *** Bandwidth limitation 
 * File list with name+size 
 * Non blocking search 
 * Using of systray (optional) 
 * Free space management 
 * Graphic of the transfert rate over time
