There are couple ways to select VRF based on source IP: VRF selection  
based on source address and VRF selection using Policy based routing  
(PBR).  I tried to implement second one in 7600 (SRC), but it was  
complete unsupported in hardware and VRF selection was performed in  
software. Regarding you question in my test lab was no MPLS-VPN  
backbone, just plain VRF-Lite. I cannot tell you about VRF selection  
based on address, but I pretty sure you don't need MPLS-VPN backbone  
as well.
