Comment (by JeremyRand):

 > Electrum-NMC is pulled in via the Python source code tarball on
 namecoin.org. That tarball contains source code from various Python
 dependencies of Electrum. It would be a lot better to pull in those
 dependencies from their upstream source (either Git or tarballs), and then
 combine them with Electrum-NMC's source (from Git).

 Updated branch at https://notabug.org/JeremyRand/tor-browser-
 build/src/namecoin (commit hash
 `4b23a0490f49e9c08c63ae5ab3c70d66be84115e`).  Electrum-NMC and its
 dependencies are now built locally from source, subject to a few
 exceptions:

 1. PyQt isn't built at all.  This doesn't matter for Tor purposes since
 Tor isn't going to use the PyQt GUI from Electrum-NMC.
 2. Locales aren't built at all.  Again, this doesn't matter for Tor
 purposes since the Electrum-NMC UI isn't going to be user-facing and
 therefore doesn't need to be translated.
 3. Protobuf definitions aren't built from source, instead the pre-compiled
 Protobuf definitions that Electrum-NMC distributes are used.  I'm fairly
 sure this isn't a problem since Protobuf is (AFAICT) only used in
 Electrum-NMC for the Payment Protocol, and that's not functionality that
 Tor will ever need to touch.  In fact, I suspect that the Protobuf
 dependency can be completely ripped out of Electrum-NMC for Tor
 distribution, which will also reduce the final binary size noticeably.

 > Prior to a release, I intend to disable IP addresses, so .bit can only
 point to a .onion

 This is implemented in `4b23a0490f49e9c08c63ae5ab3c70d66be84115e` as well,
 though I haven't tested that change very thoroughly yet.

 I'm hoping to have some additional updates within the next week or two.
