I do hope that private key isn't valuable ... :-)

Remember that 'run "echo blah > file"' is a bash command, and you need
to tell echo to respect escaped characters with "-e".
I suspect if you try enough combinations of inline newlines and flags
for echo, you'll find the solution.

You might be better off trying to shell out and create a file from a
variable's contents inside "irb" on your workstation, so you can
iterate through all the different permutations quickly without having
to do a web/cap run each time.

That key is a throw away key I was just testing with. 

I did in fact find a solution, it is a mild hack but does work.

This is the solution that I came up with:

    File.open("/home/#{user}/.ssh/id_rsa", "rb").each_line{ |line|

      run "echo #{line} >> ~/.ssh/id_rsa"

    }

Since all servers share the same github deployment key this solution does work.
