+Rotate DNS entries for mirrors more reliably.
+
+Currently the mirrors are accessed by DNS name, which can cause some
+issues when there are mirror differences and the DNS gets rotated.
+Instead, the HTTP Downloader should handle DNS lookups itself, store
+the resulting addresses, and send requests to IP addresses. If there
+is an error from the mirror (hash check or 404 response), the next IP
+address in the rotation should be used.

Use GPG signatures as a hash for files.
A detached GPG signature, such as is found in Release.gpg, can be used
adding them to the tracking done by the AptPackages module.
+Improve the estimation of the total number of nodes
+
+The current total nodes estimation is based on the number of buckets.
+A better way is to look at the average inter-node spacing for the K
+closest nodes after a find_node/value completes. Be sure to measure
+the inter-node spacing in log2 space to dampen any ill effects. This
+can be used in the formula:
+ nodes = 2^160 / 2^(average of log2 spacing)
+The average should also be saved using an exponentially weighted
+moving average (of the log2 distance) over separate find_node/value
+actions to get a better calculation over time.
