It wouldn't work.  You need to create some machinery that knows to
create two connections for a single filename.  Currently, Tramp
assumes that a single connection is sufficient.

Hm.  But the second connection is only needed for the actual file
transfer, and that happens in just two functions,
tramp-handle-write-region and tramp-handle-insert-file-contents (I
believe).  So the change required would be fairly localized.

However, there is another problem: if you use Ange-FTP for the
ultimate hop, then all the machinery in Tramp that finds out directory
contents and file permissions and suchlike won't work.  I guess it
would be possible to use Ange-FTP for this machinery, but I don't
know how.

Oh, tramp-smb also uses a non-shell for doing this.  I never tried to
use smbclient, so I have no idea what it is like.  Michael, can you
say something about where the problems were in using the Tramp code
for tramp-smb?
