Pity we will never see a genuine version of uTorrent that will support it. That was a real loss.
Sorry I am not sure why is that. Would you mind explaining?
uTorrent used to be really efficient, small memory-footprint, full featured bittorrent-client. One of the best software I've ever used to download... perfectly legal content [1] from the internets.
Now it's full of ads and performs poorly.
[1] Like all the different Linux distro install images over and over again.
Take a look at rtorrent: https://github.com/rakshasa/rtorrent
It fits the efficient, small memory-footprint and no ads requirements. "Full Featured" is subjective as it depends upon what you consider "Full Featured".
