Sure!  Take a look at:

To Lee's earlier comment about routing table growth being a worse problem than address depletion, I would note that growth has been pretty flat since the beginning of this year.  The last I corresponded with Geoff Huston, he argued that this was a purely local phenomenon in his own (Telstra) data; however, I question this as the flattening seems to be present in many routing tables (not all).  Phil Smith has argued the same; CAIDA has also done some interesting measurements that tend to confirm the flattening and suggest that it mostly reflects a drop in new small blocks...  A complicated picture.
