With small nos everyone knows each other but as the programme gets bigger other countries may also look into it and start offering organ donors. The Internet has just celebrated its 20 years and the abuse has been very wide and its applications have amazed even its founders. The Internat also has also made commerce of organs very simple and there are today many website doing this very freely across many borders. The easiest way to find a ciommercial donor is using the net - so be careful in making this programme.
