Presumably Cyberflight Ltd's operating procedures for these UAV's would include the requirement to notify the relevant ATC unit of the position, radius of operation and maximum altitude on each occasion, even when operating in the open FIR as is likely if based at Oban.
Scottish Information (in this case) would then pass this on to affected aircraft. In an ideal world!
Course if you don't talk to anyone in the FIR then, as mentioned previously, you're on your own
