I believe they have a scheme like this abroad somewhere (USA?), but it is not promoted very well. The idea is to get more people flying, and hence more work for the clubs, which has to be a good thing as long as it is properly monitored. If they are going to have this I think that one of the requirements should be for all flights by holders of one of these licences should be signed out by an instructor, as per solo flying by a student.
Mind you,with JARs, I don't know where the instructors are going to come from to do the work that is there, never mind any new stuff like this!
