 But two back-end services with Onionoo and Compass doesn't make much
 sense.  Everything that Compass knows is already known to Onionoo.  This
 functionality should then be added to Onionoo.

 maintaining two different backend services are going to be a pain, so yes
 we should probably merge the two.

 integrating those queries into Onionoo's current interface.

 This doesn't solve the discussion, but I should mention that my rewrite of
 compass.py already makes it spit out JSON rather than text strings, so
 that might be a little bit less work if you wanted to turn it into a
 service. When you run it from the command line it looks like what
 compass.py used to do, but that's just because of the print_selection call
 at the end.  For example, loading
 compass.torproject.org/result.json?exit_filter=all_relays&links&sort=cw&sort_reverse&country=&ases=AS3320
 directly will just give you the JSON.

 The client side JS is currently handling all of the display and input, but
 isn't actually doing any processing.

 have the developer resources to do that.  Can you be more specific why
 it's hard to extend Atlas to support Compass' front-end functionality,
 assuming that Onionoo would support Compass' back-end functionality?
