Hi Michael,

I've tested it with tramp-use-scp-direct-remote-copying to t and
tramp-verbose to 6 but it does not work for me: it still use the method
via a file in /tmp (which fills up my /tmp with a big file). Sorry,
there is not much more to say.

In the meantime, I was trying to implement a new "scp -3" method into
tramp but I'm slow to catchup with the tramp codebase :)
