Comment:

 I'll close this as wontfix, not because it's a bad idea, but because it
 doesn't really fit with how bridges and pluggable transports currently
 work.

Comment (by dcf):

 If it worked, it wouldn't really look like this:
  * Bridge: snowflake (Italy)
  * Russia (xx.xx.xx.xx)
  * Panama (xx.xx.xx.xx)
  * Internet
 The snowflake proxy is an extra hop before the bridge. The bridge itself
 doesn't move (that's why it can have a static fingerprint). So let's say
 the bridge is in Mexico, then it would look like this:
  * Pre-bridge proxy: snowflake (Italy)
  * Bridge: snowflake (Mexico)
  * Russia (xx.xx.xx.xx)
  * Panama (xx.xx.xx.xx)
  * Internet
 It would be an interesting thing to visualize. Though like yawning said,
 the PT architecture doesn't support anything like this. tor treats the
 transport plugin as an opaque pipe, and the transport plugin doesn't even
 have a way to report ancillary information like this.

 Going further, the question of "what snowflake proxy am I using?" isn't
 well defined. For example, the transport plugin could be using two
 snowflake proxies simultaneously, and multiplexing traffic for the same
 circuit across both of them. (We don't support that now, but nothing
 precludes it.)

 I don't think it's a bad idea, because it's not.  I just wanted to
 document that it would be a lot of work touching multiple components, that
 isn't currently planned.

 The PT interface should handle designs where the `Bridge` directive is
 essentially meaningless better than it currently does, but PTs that work
 that way didn't exist till well after the PT design was done.  There's
 been a few attempts at redoing the PT interface to be "better", AFAIK none
 of the redesign efforts really addressed this either.

 So {{{probably-bad-idea}}} I assume? Should I close this ticket then if
 the costs of making this possible are too high for infinitesimal results?

Comment (by yawning):

 This isn't possible with the current PT design as the only IP address/port
 information available to the browser (and the tor daemon for that matter)
 is the address that's supplied as part of the `Bridge` config directive
 (`0.0.3.0:1`).

 Changing this will require extending the PT interface with accompanying
 changes to the Tor control protocol in addition to the browser and
 snowflake client changes.

 Currently it looks like,

 {{{
 -
 | @ |
 -
 |
  | New Identity   Ctrl+Shift+U | Tor circuit for this site
 |
  | New Tor Circuit for this Site  Ctrl+Shift+L | (gitlab.com)
 |
  | | o This browser
 |
  | Tor Network Settings... | o Bridge: snowflake
 |
  | Tor Network Settings... | o Russia (xx.xx.xx.xx)
 |
  | | o Panama (xx.xx.xx.xx)
 |
  | Check for Tor Browser Update... | o Internet
 |
  | |
 |
 -
 }}}

 How it should be,

 {{{
 -
 | @ |
 -
 |
  | New Identity   Ctrl+Shift+U | Tor circuit for this site
 |
  | New Tor Circuit for this Site  Ctrl+Shift+L | (gitlab.com)
 |
  | | o This browser
 |
  | Tor Network Settings... | o Bridge: snowflake
 (Italy) |
  | Tor Network Settings... | o Russia (xx.xx.xx.xx)
 |
  | | o Panama (xx.xx.xx.xx)
 |
  | Check for Tor Browser Update... | o Internet
 |
  | |
 |
 -
 }}}

 Just like with obfs4 for example.


 This will also better reflect the nature of snowflake to the lambda user
 as a temporary bridges PT.
