A "REXX:" device would be a big win, making it much easier to add REXX
ports to programs. The way I see it working:

In a 'C' program:

	REXXPORT = Open("REXX:name", MODE_NEWFILE);

The driver enrolls "name" as if it was a REXX compatible program.

In a REXX script:

	ADDRESS name command

The REXX driver grabs the command from the REXX string and sends it to the
file opened above.

Back to the 'C' program:

	nbytes = Read(REXXPORT, buffer, maxbytes);

This returns the command as a line of text from the file.

	Write(REXXPORT, response, nbytes);

And this sends a response string back to the REXX script.

Of course, you can effectively do the same thing without this by using a
pipe and calling
	open('name', "PIPE:name", 'Write')
	Writeln('name',command)
	result = Readln('name')
	close('name')

in your REXX script, but unfortunately I don't know of any PIPE: device that
handles multiple opens/closes the way it needs to work for this application.
Besides, it's ugly.
