     The forwarding hardware is generally going to be the limit, and
that's going to be painful enough as we approach a half million
prefixes. 

There are techniques to fix that. For example, Simple Virtual Aggregation
http://tools.ietf.org/html/rfc6769


I'm not sure, if hardware vendors will implement something like this. I
expect they'll sell you router with larger hardware FIB instead.
