Not sure what this has to do with the beta list, but...

There's no easy way to do it, because XEmacs caches the home directory
when it starts up, and in any case you can't change its own
environment.
If you're happy with just having ~ expanded, you could intercept
expand-file-name, like so:

(defvar temp-home nil "temporary home directory - must include final /")
(fset 'real-expand-file-name (symbol-function 'expand-file-name))
(defun expand-file-name (name &optional defdir)
  (real-expand-file-name
    (if (and temp-home (string-match "^~/" name))
      (replace-match temp-home t t name)
     name) defdir))
