If you are really serious to see MLAT plane on your local map, then it is possible if you feed Flightaware. They feed-back MLAT data to the feeding station which displays MLAT planes on local map of the feeder station.
You can feed Flightaware from Windows or Mac computer if you install Planeplotter software. I think Flightaware provides a free of cost key for Planeplotter to those who feed them.
Alternatively you can feed from a Linux computer. The easiest way is to purchase a Raspberry Pi, a DVB-T (RTL2832U+ R820T2) dongle, and a home made or commercial antenna.
On RPi's microSD card, install Raspbian OS image, then install dump1090 and Flightaware feeder piaware.
