Sounds to me like you need shadowfile.el. With this package, you could
define clusters, which implement a similar feature as you apply, keeping
several files in sync on different hosts, once one of the files is
changed.

Unfortunately, shadowfile.el lacks the same problem as rlogin.el does:
it is based on ange-ftp. So it must be adapted to Tramp. I've started
this rewrite a while ago, but it is half-baken only. Maybe I shall
continue this work, with pressure from you :-)

For the time being, we could try to solve your other problem, that you
couldn't use Tramp due to your special ssh client. Do you like to send
me the details, that we could find out how to configure Tramp to
support you?

Best regards, Michael.
