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
