Experience shows that a series of at least 40 ground stations is required to cover the UK down to about 2000 feet.....even more for low level coverage.
By my reckoning thats getting on for £100,000 of kit plus humungous server costs and all the hassle of setting up a network.
Not very cost effective , especially when you can get PP for a few quid.
Slightly delayed it may be , but for airways traffic it is "out the window " accurate.
If you would like to provide a secure server capable of taking the Planeplotter load , I'm sure Bev will be happy to give you real time Mlat

....Subject to stringent security checks of course
