A bit brainstormed for the moment ;)

* Core and GUI are independent. They communicate over TCP socket.
12
** It is possible to launch the core without the GUI. The core does not depend of any kind of graphic library.
13
** If the GUI crashes then the core remains.
14 22 Greg Burri
* Designed for LAN usage (full trusted peers and very high speed transfers).
15 18 Greg Burri
* Efficient (very low cpu usage).
16
* Distributed download (multi peer downloading and no central server).
17 27 Greg Burri
** Quicker peer 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 to a quicker free peer.
18 16 Greg Burri
** Rarest parts first.
19
** A part can be resumed from any peer.
20
** 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.
21 18 Greg Burri
** Recursive folder downloading.
22
* There is a general chat.
23 25 Greg Burri
* Multicast UDP for services discovering (maybe UPNP). Each peer announces periodically he is alive with a multicast message.
24 18 Greg Burri
* MDI GUI with GTK2HS.
25
** A panel to view the current peers.
26
** A window to view the current downloads (leechage) and one for the current uploads (seedage).
27
** A window for the chat.
28
** A window for searching.
29
** Some windows for each file browsing.
30
** A modal window for the settings.
31
*** The shared folders.
32
*** The incoming folders (take the first if enough available space disk otherwise the second and so one..).
33
*** Bandwidth limitation.
34
* File list with name+size.
35
* Non blocking search.
36
* Using of systray (optional).
37
* Free space management.
38 19 Greg Burri
* Graphics of the transfer rate over time.
