how to persuade shell/ssh mode to use remote dynamic completion.

[Simon Allfrey]

Most machines I connect to will only accept secure connections.
Under ssh remote directory tracking (via tramp/ssh), while possible can
be
very slow. In the case of gateway scenario where the remote machines
do not support the inline tramp methods, directory tracking becomes
impossible. Thus I look to the remote shell to support
command/filename completion but I want to avoid if at all possible
using the unfriendly term mode.

I have been hacking into shell.el/comint.el to try to pass a literal
TAB(remotely bound to completion) to the remote shell and read the
resulting completion. However, even after attempting to remove all
output-filter-functions I get nothing back.

Any chance of some code which will replace the current input line
with the remote shell's idea of it's completion?
