Yeah, but that virtual ground brings with it it's own set of problems. For instance, it has to both sink and source current, so you can't just use a 3 terminal regulator to create the midpoint, although I've seen schemes with a resistor from virtual ground to negative supply, but that's not very power efficient - the resistor needs to see, say, 10x the maximum sink current.
You might look at the LT1118-2.85 "Supply Splitter". It is able to do either sink or source, as needed, unlike an ordinary regulator.
