Thanks!

I'm not sure what your question is. The available interfaces to the gateway -- i.e. the cleartext side that is marked in red on [1] -- are:

* the "tahoe" command-line tool [2]

* your unadorned web browser, even with JavaScript turned off, pointed at the gateway over localhost (or over SSL to a remote host, or whatever you want)

* your FTP or SFTP client

* FUSE (although in a Rube Goldberg-esque setup where FUSE is chained to the aforementioned SFTP server through the "sshfs" tool; Like a Rube Goldberg device, it actually does work once you get all the pieces set up next to each other.)

The semantics of what you can do with this are described in summary here:

https://tahoe-lafs.org/trac/tahoe-lafs/browser/trunk/docs/about.rst#access-control

And in much more detail in the documentation pages linked from there.

Does that answer your question?

P.S. This is a test of charset handling through GNU screen, mutt, and GNU mailman: ¹

(That should be a superscript "1".)
