Not that I have used it for myself, but here's a NEWS entry about how to
do it with CVS guile:

--------------------------- Begin NEWS -----------------------
** It's now possible to create modules with controlled environments

Example:

(use-modules (ice-9 safe))
(define m (make-safe-module))
;;; m will now be a module containing only a safe subset of R5RS
(eval '(+ 1 2) m) --> 3
(eval 'load m) --> ERROR: Unbound variable: load
---------------------------- End NEWS ------------------------

I can't answer the second question, sorry.  However, this is certainly the
right list to as such questions.

Best regards,
