You can also use abbrev.

(define-abbrev global-abbrev-table "D0" "~/My Documents/Projects/xyz")
(define-abbrev global-abbrev-table "D1" "/sshx:myuser@unix1.abc.def.com:/home/myuser")
(define-abbrev global-abbrev-table "D2" "/sshx:myuser@unix2.abc.def.com:/home/myuser")

and then type C-x C-f D0[C-x ']

Take a look at uniquify.el.  It comes with cvs emacs... I don't
remember if it was part of 21.3 or not... if it wasn't you can search
around for it via google.  It's a nice package for this type of thing
and you can probably configure it to give you what you want.

(require 'uniquify)
(setq uniquify-buffer-name-style 'post-forward)
