vcdiff is a shell script, which comes with Emacs. So you can copy your
local version to the remote host, let's say into your home
directory. Don't forget to set executable permissions.

The call of vcdiff is hard-coded in `vc-sccs-workfile-unchanged-p' and
`vc-sccs-diff'. I wouldn't change that.

Assumed you run Tramp 2.1 (part of Emacs 23.1), you can extend the
remote $PATH to look in your home directory:

  (add-to-list 'tramp-remote-path "/my/home/directory")

Best regards, Michael.
