I think I didn't say "yes" because several other people on the net said
so already.  Yes, environment variables are files in ENV: under 2.0.

You may request notification when a file changes.  DOS has a couple of
calls (StartNotify() and EndNotify()) through which you can arrange
to learn when a file changes.  For example, IPrefs waits on notification
from a bunch of files including ENV:sys/pointer.ilbm.  Try saving a
4-color brush from DPaint to that name.  IPrefs will pick up the change
and make it your new pointer!

Notification is very useful for Preferences and dynamic data linking.
