Yes. Search the file archive for:

     share memory

You'll find examples by Mario Steele, Jason Mirwald,
Jordah Ferguson and Elliott Sales de Andrade that
allow two separate Euphoria processes to
share memory, and even pass Euphoria data back and forth.

That sounds too complicated, especially since
DLLs can't share Win32Lib variables or even routine id's
with the main program.
However they can share machine addresses of Euphoria
routines, and in 2.4 you can call a Euphoria
routine given its call_back() address. Andrea Cini
uses this trick in EuWinGUI.
