Is there a way to do this? In other words, is there a way to
set env variables that ANY user and ANY application can see?

No, environmental variables are a per-process thing. Child processes
inherit the state of their parent's environment, but that is it. If
you need inter-process communication you have to use IPC*, a file, a
database, or some other external resource. Take a look at
IPC::SharedCache** or one of the other IPC modules*** on CPAN.
Depending on your needs a simple file might suffice though.

* that is what it stands for after all.
