Narrative:

I departed so as to remain clear of fll class C airspace and below floor of mia class B airspace. An airliner was observed approximately 10 miles west of fll inbound to fll below the normally observed altitude of airliners inbound to fll. The recent addition of ads-B allowed timely visual observation of the traffic and we altered our route in a normal fashion without incident. There were several VFR aircraft in the area. I do not believe any FAA regulation were violated. This report is being filed to point out an area of potential hazard that could be addressed by modifications to the mia 'B' &/or fll 'C' airspace(s).I believe aircraft departing/arriving the area to or from the northwest should not be allowed to become possible conflicts with ILS inbounds to fll. There exists an area 10 to 15 miles west of fll where VFR aircraft can operate at the same altitude as aircraft established on the ILS approaches and no ATC clearance is necessary. Another area of concern is the portion of mia class B airspace 15 miles west of fll where fll ILS arrivals can be at 2500 feet and other inbounds are descending below the 4000 foot floor of the mia class B airspace and also into the previously mentioned class east airspace when only see and be seen VFR flight rules are providing separation of aircraft established on published final approaches that are heavily used. I would like to see modifications as needed to provide a sterile protected environment to fll instrument inbounds. Generally the inbound aircraft over 20 miles are of sufficient height to lessen the conflicts but when establish on the final I believe extra protection is warranted.
