While emacsclient from 22.1 cannot open a new frame, you can still use
it to evaluate lisp (yes, I actually tried). You can retrieve the the
invoked emacs binary from the running server by calling

 emacsclient -e '(expand-file-name invocation-name invocation-directory)'

You just have to be aware that an older emacsclient will prefix the
output with '-print'.
