I like the principle, but don't see the point of just being able to buy them - that makes it little more than a discount voucher scheme. Even at that, I don't think I would go to the bother of exchanging my sterling into porty pounds just for a 5% discount. I'd suggest you need to 'earn' them, which maybe ties up a bit with Seannie's time bank idea.
However, to me, the best way to earn them would be as a reward for shopping local - each participating retailer would give you some porty pounds when you shop with them. These same retailers would accept the porty pounds as payment. It could be tuned work out at the same 5% discount, though the denomination or exchange rate would need to be tweaked so that you could collect something on small value purchases.
Retailers would be more inclined to get involved as it would promote repeat local shopping. Since they will both give out and receive, those who receive a surplus would sell to those with a deficit, thus ensuring that the cost to a retailer is always in proportion to the amount of real money spent in their shop.
