I've pushed a change to the Emacs master git branch, which allows to
change the application in `with-connection-local-variables'. The Elisp
manual has been extended with
--8<---------------cut here---------------start------------->8---
-- Variable: connection-local-default-application
The default application, a symbol, to be applied in
‘with-connection-local-variables’. It defaults to ‘tramp’, but in
case you want to overwrite Tramp’s settings temporarily, you could
let-bind it like
(connection-local-set-profile-variables
'my-remote-perl
'((perl-command-name . "/usr/local/bin/perl5")
(perl-command-switch . "-e %s")))
(connection-local-set-profiles
'(:application 'my-app :protocol "ssh" :machine "remotehost")
'my-remote-perl)
(let ((default-directory "/ssh:remotehost:/working/dir/")
(connection-local-default-application 'my-app))
(with-connection-local-variables
do something useful))
This variable must not be changed globally.
--8<---------------cut here---------------end--------------->8---
Does this suffice?
