I cant see why this would/should be implemented into a "client". I didnt read indepth, just waht's stated in this thread, and yea, there are ways to run BT tracker clients on the server/tracker end, correct? So, basically, if a torrent on the tracker had low seeds, the server/tracker-side client would kick in, and start helping out by sending pieces out. Addressed to the peers, and From the tracker address. This seems more of a server side implementation. Like, for example, I believe when revision3.com, commandn.tv, and other torrent based pod/vidcasts release new episodes, they use something similar to this. remote machines, all over the world, to help spread out the torrent, on high speed connections until a reliable seed/peer ratio picks up, and tags along, at which time, they would disconnect their main servers/web seeding.
