@GooRoo: The feature you talk about was suggested some time ago (some time means Summer 2003) during the Queue-Discussions in the GDF.

Sadly it still isn't realized. It seems we will first have to find some developer of a small servent, who implements it and shows, that it truly does work (the problem was the same with swarming and automatic requerying (which evolved to the download mesh).
Maybe you could ask the Programmer of Phex (Forum in Gnutellaforums). He sometimes does work on donation-basis for deciding which feature to implement next.
