[comp.sys.mac.programmer] Simple IPC code?

The developer's Q & A stack from Apple mentions a simple procedure for 
implementing interprocess communication until System 7.0 is ready.  They 
suggest creating an Init that installs a driver and initializes it.  The
driver just sets aside some space in the system heap and supports one status
call that returns a handle to that space.  They then go on to talk about 
more sophisticated calls that the driver might support.

I'm wondering if anyone has already implemented this simple init and driver
combination?  I need to pass strings back and forth between two
applications and would rather not reinvent the wheel.  If you have LSC source
code to handle simple IPC I would really appreciate a copy of it.
Alternatively, if you can send me any sample init or driver code that
would help me write my own routines that would be great too.
