I did get connected using the sftp command line client.

{{{ls}}} fails.

{{{mkdir testing}}} created a directory that I can see with {{{tahoe ls}}}.

.... very interesting....

I copies a files {{{tahoe cp path/to/file alias:testing/}}}, and was able to
do see it with {{{ls testing/}}} in sftp.

I then attached to sftp://localhost:8022/testing with Dolphin, and I can see
the file.

I can copy the file form the sftp-mounted directory to a local directory
with Dolphin.

I cannot open the file directly from the sftp-mounted directory because
other programs don't have access to the kioslave.

So the problem with with the root directory of the alias. Apparently, not
all of the information required for ftp/sftp is being passed by tahoe
through the ftp/sftp protocol.

At the very least, files can be copied from *some* tahoe directories to the
local filesystem.


Using Nautilus, I can attach to the sftp server. I chose "SSH" as the
connection type (this will need to be documented).

In Nautilus, I can double-click on a file, and Eye of the Gnome will open
it.... Gimp will open it.
