The same could be done in the UK and indeed does happen already at some place... forgotten the name of it but it is some company-owned runway near Liverpool or something like that, which uses a remote controller which is paid by the runway owner.
Barrow/Walney Island. It's used for BAE's dwindling B200 fleet, run under the authority of the boss of BAE Barrow. The UK requirement is for a controller to sequence traffic to the IAF, so essentially as a minimum to "control" a hold & procedure OCAS. No reason at all why it shouldn't work with a correctly trained category of AFISO (indeed, a number of training approaches work on this basis, technically to be conducted only in VMC and for training purposes) in the future. We can hope... Especially with GPS approaches, already a nicer way of flying most NPA!
