Hard, but possible.  The ways I could think of, in the increasing order 
of complexity:

	- disk file
	- clipboard
	- TSR loaded ahead of Windows
	- device driver

The problem is the same in both cases: Windows programs run in a 
different virtual machine than DOS programs; and every DOS box is a 
separate virtual machine.  Different virtual machines have separate 
address spaces.
