 gman999 thought about setting up two bridge authorities behind a single,
 virtual IP address. This will make our bridge authority more resistant to
 hardware failure because if one goes down, there's still the other one
 that continues operations.

 Once set up, both bridge authorities would then separately sync their
 bridge descriptors to BridgeDB, which  expects a single directory of
 bridge descriptors, so we will either have to 1) teach BridgeDB (and Tor
 Metrics) how to handle >1 directory of bridge descriptors, or 2) write a
 tool that takes as input an arbitrary number of directories containing
 bridge descriptors and then produce as output a combined "view" of these
 descriptors. We agreed to first take a look at a tool that can combine
 "views" because it would simplify our processing pipeline and it may be
 easy to do with Stem.
