Comment (by andrey):

 Testing with FTP instead of SFTP or SCP:

 1. install proftpd on a node, edit /etc/proftpd.conf to set up anonymous
 FTP access to /var/proftpd (see commended-out "anonymous" section at the
 bottom for how to do it).  start the server via:

 {{{
 /etc/init.d/proftpd start
 }}}

 2. install ftp client on another node

 3. set up blinding such that the client node and server node are more than
 one hop apart

 4. make a big file to test with, for example:

 {{{
 dd count=50 bs=1M if=/dev/zero of=big-file.bin
 }}}

 and note its md5sum

 5. ftp to the mesh address of the server node, log in anonymously (ex:
 'ftp', no password) and cd to 'uploads'.  'put' the big-file.img there.
 On the server node, check the md5sum of the uploaded file.


 In my test, the md5sums do not match:

 {{{
 25e317773f308e446cc84c503a6d1f85 (client)
 b0b9dab13a68502e073764d71d0b7ccd (server)
 }}}
