How do you think the instructors feel?!? The prospect of a long nav with a land away almost makes me giddy. A ludicrous amount of a flight instructors time is spent within a 1 mile radius of the airfield.
If I was an instructor, and I had a punter who has more than 2p to rub together (and perhaps 50% do) I would suggest to him (or her

) that we pop over to LTQ (etc) - BUT that this will increase the cost of his PPL BUT trips like that will make him able to fly from A to B which he won't be able to do otherwise because a PPL largely banged in the circuit is virtually useless.
I would expect to get some takers...
It is not illegal to train pilots who can use their bit of paper for something half useful
In the FAA system, loads of pilots did their papers (especially the IR) on a long x/c journey around the USA, or doing business/etc trips around Europe. It is more cost effective than under the JAA system because you can use a freelance instructor; in the JAA system you carry the RF or FTO overhead everywhere you go. The end result is that, by and large, FAA paper holders can fly from A to B whereas JAA paper holders can fly from A to A only
