I have a similar setup, combining a dedicated server and a shared VPN. On the DS I have two outward routes: one for BitTorrent, and the other for everything else. BitTorrent traffic is the one that goes through the VPN. In addition to this, I set up a private VPN between the DS and my home devices, and the DS is configured to route the traffic from this private VPN through the shared one if I choose to. So far (about nine months in) I haven’t gotten any DMCA complaint, and can seed torrents without having to care for upstream bandwidth at home.
