You can eaily propagate the SSH_* environment variables to other
sessions via scripting, if you store the variables in a known path.
You don't have to change the registry for that to work.

Try xemacs.  It has a Windows GUI fallback mode if there's no X display.

You can start it from the start menu via a bash script which pulls in
the SSH_* environment before starting emacs.

Don't get me wrong, I'm not opposed to include win-ssh-agent into the
distro if it gets enough votes, but there are simple ways to solve this
problem without a Windows GUI application.
