Facebook, Wordpress and Mobile phones...

I don't know if your inbox is anything like mine lately, but many emails I receive are promoting wordpress/facebook and or mobile phone related products/services.

This got me thinking and doing some research and I have come up with a way to incoporate all three and have facebook pages as the front people see and using qr codes that can be scanned by mobile phones and take users direct to a payment page that can be redirected back to a download etc.

Can anyone apart from me see the potential in this?

Please comment with thoughts and experience.
