Yeah, you are right. But the way you illustrated is a little bit 
complex. That's why we put it into the limitation and gaps part. And as 
you explained below, the PeerMode usually used when a peer firstly 
connected to the tracker. Once they login to ppsp system and finished 
data transmission, the PeerMode may not represent their status. We are 
hoping to provide a simple way to solve this problem, which not defends 
peer's willing. For example, peers may change their PeerMode once they 
gets the whole content and are willing to share it with others via 
STAT_REPORT message. While another option is that PPSP system change it 
automatically (Just as you mentioned). For those people who are not 
willing to share the content, they could send CHONKE message to express 
their willing.

Thanks. I just read this part again.
