Comparison: New Apple Patent and Starbucks vs Digital Pizza Ordering Pioneer Papa John's

All the buzz about Apple's recent patent filing, where Steve Jobs and company are apparently cooking up a wireless ordering/line cutting system that'll launch with Starbucks ... got me thinking and snooping around for similar things.  I stumbled on the apparent digital dominance of Papa John's - at least dominance in the pizza industry - when skimming through a press release where Papa J talks up how it's preparing for an end of the year pizza rush.  The last round of regular season NFL games this weekend, leading into New Year's, apparently makes for a lot of dough tossing.

Papa John's is touting its advance online ordering capability, at PapaJohns.com, where you can place an order for pizza online - with specific pick-up or delivery windows - up to three weeks in advance.  And Papa John's claims it is the only national pizza chain to offer both online and text ordering at all of its U.S. locations. 

Papa John's has offered online ordering since 2001.  The text ordering system, available since November 15th of this year, is interesting as a comparison to what Apple and Starbucks are cooking up.  It's obviously not intended to solve long lines like the Apple/Starbucks deal is.  It's a nod to the fact that nearly 50 percent of mobile phone users use text messaging.  The four step process is as follows:   

1. Consumers first register at papajohns.com and save their favorite orders, delivery and payment preferences with the "Favorites Wizard." (you can store four favorite orders)
2. Once registered, consumers can simply text FAV1, FAV2, etc. to 4PAPA (47272).
3. Papa John's then sends a text message detailing the order and requesting confirmation.
4. Consumers press Y1 to confirm the order for FAV1 or N1 to change the order.  Once confirmed, the closest Papa John's restaurant processes the order.

Here's an animated video demo of the text message ordering process.  So with this system, Papa John's can take a text message order ... from any phone that has texting capability.  I'm wondering why Starbucks would not choose to implement their own system, like Papa John's has, that can accept wireless orders from anybody, and not just iPhone users.  So this is my question:  what is the special sauce that Apple is cooking up that might make Starbucks choose it over a more open plan that could potentially serve any consumer with wireless texting capability?
