how to determine the login shell?

Ahhh, OK. I see your problem:  SSH doesn't (and better not) 
back-propogate remote environment variables into the client.

It does let you execute commands on the remote host, though.  What about 
executing "sh -c echo $SHELL"?  sh is universal(as is its variable 
representation), and the execution of it thus does not overwrite the 
$SHELL from the spawning shell.
