You can hack something together using XREGISTERED and the
XMANAGER. You are still using common blocks, but they're RSI common
blocks and the programmer doesn't have to get them right in every
single program file.

I use the system variable technique, storing the object reference
to an IDL_CONTAINER which acts as a dumping ground for user
information and preferences. A system variable is stable across
platforms and versions of IDL, and the container makes it easy to
extend and modify the information stored without having to find and
edit every single program file that uses the global information.
