[cisco-bba] Dynamic routing over L2TP LNS

Not really, the same principles apply, seeing as you are using vrf's are 
you planning on running MP-BGP with MPLS for this? in my experience 
EIGRP seems to integrate the nicest out of all the IGP's into this 
scenario, but anything will work with proper design.

Also if you plan to run QoS on your L2TP ppp sessions then you will 
probably want to look at enabling multilink ppp, last I checked(12.4(18) 
7206) this was still required in order to get QoS to work effectively, 
without it no shaping would occur on the virtual-access(on the lns), I 
really wish they would fix that up...
