Actually it doesn't seem like too much of a hack, except that it seems to be not a realtime operation (otherwise why would they need to contact your script?). Good points: 1. PayPal contacts your script to tell it about the transaction, this script could be anywhere. 2. Requires verification from PayPal. 3. Encrypted transaction identifier from PayPal means you don't have to protect your receiving script with SSL. Bad point: 1. Sounds like it's not realtime.
