Was this commented out from the code already released?
Did you notice it's all in BTC and not VTR?
Just taking a look at what's what.
I think the @vtorrent implementation will be much better than this, probably closer to how uTorrent or similar actually looks and functions.
It seems to be a bridge to run the actual BitTorrent client. So there must be some two-way interaction with the QT wallet. So you should really see the benefits of two worlds in one place, either use each one on their own or together.
