You can do it by putting Tet's bit of bash magic into the /etc/profile 
on all your remote hosts. However, you make it's execution conditional 
on the presence of an environment variable you set, and then put this 
environment variable into your sshd_config in an AcceptEnv directive, 
and in your ssh_config in a SendEnv directive.

That way, users who have the environment variable set will have it 
propagated wherever they go, and /etc/profile will do the appropriate 
magic you've set it to. Users without the environment variable set will 
see no change in behaviour.
