Just for completness sakes, if your reading this and thinking your not
sure what ITN is, that would be because dave meant to say "IPN".
The only think I have to say is that perhaps we should change "PayPal"
to be "Paypal" so that the style throughout the code is consistent?
Otherwise, thats sterling work; really like what you've done with the
DispatchPf stuff - had no idea that you could break it out into parts
of the framework like that. Super sweet!
I've just updated Paypal.scala with a bunch more scala docs too.
Cheers
