I got this stuff pretty much straight from the horse's mouth as it were... the Dutch training provider is doing this based on extensive experience with distance learning and with candidates from various backgrounds. They group the subjects into three different modules, each of which can be studied individually or together and the distance learning bit is supported by live evenings where they do revision and brush up before setting off on the exams. These are done in-house as they are an exam centre for Austro Control. See here:

It's a different approach compared to some other countries/training providers but the school has been around for a while and, in this particular situation, is a pretty good match for what Dylan is trying to achieve: an EASA PPL in The Netherlands but using English language materials and exams.
