Talking of Scotland, take a look at what just one PWP who lives and works there (36 years old and dx only a year), has acheived on his own in a very short period of time. Particularly the media coverage he has attracted in the last month.

Also Tom's suggestion about a simple global data base of PWP has enormous potential across a huge range of PD fronts.
Take the excellent "Pennies for Parkinson's" USA based initiative and how easily it could become a global fund raising initiative with such a data base.
