Are there any roadblocks that prevent us from doing the following?
1. Remove the hard-coded bridge_prefs.js in the TBB.
2. Set meek as the default pluggable transport in the TBB.
3. Use meek to acquire an up-to-date bridge_prefs.js from, say,
torproject.org.
4. Use the information from the acquired bridge_prefs.js to connect to Tor as normal.
Ostensibly, this doesn't do a better job of hiding bridge addresses. However, it allows us to modify bridge addresses without releasing a new TBB.
