You might want to experiment with QPPB (QoS Propagation using BGP). Admittedly, I've never tried this, but I've read *somewhere* that you can propagate QoS classification via BGP (carried as BGP standard community, I think). Since you're talking about VRF, I assume that you're running MPLS in the backbone? Should be fairly straight-forward to combine QPPB with MPLS, since you would already be running (MP)BGP. You just have to make sure you're sending both standard and extended communities between your PE routers.
Oh boy... I'm guessing that you should be able to. My (very limited) understanding of QPPB is that the QoS PHBs are translated into BGP standard community at ingress PE router, while the egress PE router will perform the process in reverse, i.e. translating the QPPB back into "normal" QoS PHBs (i.e. DSCP, IP Prec, or whatever). Hence, at egress, you'll get the usual DSCP/IP Prec/whatever that you can perform the appropriate action on at the egress interface to your customer
