The best suggestion I can offer you is that you should look into the folks who are doing this type of setup in the DSL world. Centrally authenticating / servicing 1000 to 100,000 subs is not un-common in the wireline world.
Redback SMS500 or SMS1000/SMS1800 would easily terminate 1000 subs. You could use L2TP Tunnels across the network for the Edge Routers to the Core/Central PPPoE Server to accomplish what you are looking to do. Redundancy is normally achieved with the use a combination dynamic routing (BGP / OSPF) and using L2TP.

We have a mix of access points from Alvarion, Trango, MikroTik, Canopy, and others. We're currently running a distributed PPPoE model with MikroTik PPPoE concentrators. We're concerned about MikroTik's longevity, reliability and support as we move towards a more centralized PPPoE model where all our sessions terminate at a CO. We're looking to migrate over 1,000 customers, currently across 15 or so concentrators, to one single concentrator with either load balancing or redundancy. We're also trying to keep our decisions based around a future IPv6 implementation. My question is if anyone has had any experience in deploying large scale PPPoE with a centralized methodology. I have investigated the Open Source options such as rp-pppoe and others but have found that they don't offer any load-balancing or redundancy options, which are important considerations when moving to a centralized model. These packages also don't offer any type of integrated rate-limiting or burst-limiting based on RADIUS. Does anyone have any experience with other types of centralized authentication for customers that support IPv6 and include integration of rate-limiting/bursting? I have reached out to a Cisco integrator, ImageStream, Fine Point Technologies (http://www.finepoint.com/servpoet.html), and some others to find solutions.
