I trying to build an application that is using the torrent technology to make it easier to share the files between friends.
The question are, is it possible to modify a torrent at runtime and that everyone using the torrent then are possible to fetch the update version of the list of files. Could be that a file is modified, added, deleted etc and the it should be changed in the torrent file. The file distributed among friends is fairly easy, but will any "torrent-lib" be ok with it?
I haven't digged down to the torrent-spec entirely but I have search a lot and can't find any other that have asked this question.
Also would the same work if using magnets instead of torrent files?
You can't modify a torrent after creation, for that will modify it's hash and therefore create an entirely new torrent.
