If you're running those subscribers on an NPE-G1 right now then you should be fine. If you scale up you have the option of dumping an NPE-G2 in there. No idea about licensing. As far as configuration goes there should be a pile of examples out there on how to build an L2TP LNS. Here I've only dealt with L2TP in a LAC role as our Redback routers handle the final step.
If you weren't already aware, your Ethernet path will need to be able to accommodate a higher MTU for the L2TP-encapsulated stuff. This won't be a problem with the NPE-Gx's onboard ports. Are you running PPPoE for your wireless subs as well?
