Its hilarious that Controllers here are being flamed for daring to offer a separation service to VFR aircraft. In Australia in Class E airspace under the new NAS system, the controllers were trained purely by the book procedures and that is, IFR recieve traffic information on known or observed VFR traffic. Thats it, no separation to be provided. This was done, and a 737 almost cleaned up a Lancair, and may have succeeded if not for a TCAS RA, near Brisbane. The controller was publicly called "criminally negligent" for not stepping in and positively separating the aircraft, even though he followed his training to a T and passed traffic on three occasions. So which is it, ATC steps in and separates, and gets told by the pilot to butt out, or sits back and watches them almost hit, and gets accused of being negligent.
