Whatever the future of the JAA, it doesn't concern me any more, I'm out of there!
However, there are some misconceptions in this thread which I might be able to help sort out concerning licensing privileges.
The holder of a valid PPL issued in accordance with the provisions of ICAO Annex 1 can fly a UK registered aircraft in what the CAA will translate as "day VFR" only. So the holder of an FAA PPL or an RSA PPL could fly a G-registered aircraft in UK airspace. To fly said machine in non-UK EU airspace may be possible but the pilot should contact the individual authorities for permission which Might be granted.
Beware of calling the IMC rating a JAA rating - it is not. It is a UK only rating and as such only valid in UK airspace.
To The Guvnor, you should be OK to ferry a UK registered aircraft to South Africa on a UK validation of an appropriate pilots licence issued in accordance with ICAO annex 1.
Flying is fun - enjoy it
