If you just need MPLS VPNs (VRFs) on the CE then you might want to try Multi-VRF a.k.a. VRF-lite. If you have 12.2T with IP Plus or higher, or 12.3 with SP Services feature set, you can configure VRFs. You then have a logical interface per-VRF between the CE and PE, instead of needing a label-switched path, no real MPLS. Frame relay is nice for this.
