Well, you might check whether `path' is already a remote file name. In
this case, you do either nothing, or you try to open the file on the
remote machine as root.
It would also be nice, if the cursor goes to the same position in the
new buffer. And maybe even inserts the character you have typed :-)

Well, what about remapping the commands? I believe it is more clean than
