Open source Bitcoin POS for Digital Goods

[thefiniteidea]

Does there exist open source code for a digital Bitcoin POS?

For example, if I'm trying to sell blog viewings by creating individual bitcoin addresses to a specific customers, is there code that has been written to make implementation of this simple already?

Thank you!!

(noob question, im so sorry for asking this when im sure its been asked a million times. i have no idea how to phrase it properly for the search)
