-------------------------------+----------------------------
 I just found out that clients advertise their IP to the introducer!

 Storage servers on a hidden service grid will set their `tub.location` to
 their .onion address and send that instead, but clients do not need to be
 connected to so they don't have their own hidden services and won't set
 `tub.location`.

 I've been running a hidden service grid for a while and just now realized
 (via the screenshots in [https://tahoe-lafs.org/trac/tahoe-
 lafs/ticket/1931#comment:17 this comment]) that the introducer has a list
 of clients. I have not yet restarted my introducer to confirm that Tor
 clients are listing their IPs there, but I don't see why they wouldn't be
 since they don't have `tub.location` set.

 Is there any reason clients need to tell the introducer their addresses at
 all?

 I think the section of `configuration.rst` that mentions hidden services
 should include a caveat about how Tahoe is not yet actually ready for
 anonymous use, mentioning this issue as well as #1942.

 I'm setting the milestone to 1.10 in hopes that this documentation change
 can make the upcoming release.
