As far as UTorrent is concerned(Just giving an example, don't flame me ). The file space is reserved as soon as the torrent starts, so unless you can actually combine TF with phpuploader there's no possibility that i can see here.

There has to be an indication from TF, saying that the download has completed and then the phpuploader script runs. This my friend is upto lifetalk and somik.
