A bit brainstormed for the moment ;)
- Core and GUI are independent. They communicate over TCP socket.
- It is possible to launch the core without the GUI. The core does not depend of any kind of graphic library.
- If the GUI crashes then the core remains.
- 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 folders (take the first if enough available space disk otherwise the second and so one..).
- Bandwidth limitation.
- File list with name+size.
- Non blocking search.
- Using of systray (optional).
- Free space management.
- Graphics of the transfer rate over time.
