	Of course it is possible to run out of Virtual Memory if by 
	"run out" you mean "having no more space in which to store 
	things".  Virtual Memory is just a way of mapping a large 
	(but finite) ammount of mass storage into the processor
	address space.

	Of course it is not possible to run out of Virtual Memory if
	by "run out of" you mean "execute directly instructions stored
	in".  Your program has to be loaded into physical memory before
	it can be executed.

	I hope this covers both of the answers.
