Arduino and LiveCode and RadioShack and rambling on

Some context (A Contest!):
RadioShack has recently [ https://www.radioshackdiy.com/ ]returned to its
DIY roots. Partnering with Make Magazine, Instructables, Popular Science,
Wired, and Popular Mechanics, the Shack is sponsoring "The Great Create"
to spur the use of the parts and technologies they sell. Which is why they
now sell Arduino kits, Maker kits, Seeed Studio add-ons, etc. 

They are having a contest they invites entrants to create projects that
tie together mobile devices and the Arduino (both of which RadioShack
sells, of course):

Contest info on The Great Create blog:

Contest or not, this is a great vehicle for teaching programming,
hardware, mobile networking, etc. etc. 
Maybe even using LiveCode.

So, forgive my cluelessness......

I'm trying to imagine a way to talk (ideally, bidirectionally) to an
Arduino using a LiveCode app on iOS.
Does anyone have experience with this?

My only ideas are using [ http://www.redpark.com/c2db9.html ]the Redpark
serial cable (not sure if we can talk to it via LiveCode, maybe using
mergeExt?)
or...
via a good ol' web protocols (using a wireless connection to the Arduino -
a wifi-enabled [ https://www.sparkfun.com/products/11663 ]NetDuino?)
or...
A combination of these, as the [ http://www.ladyada.net/make/xbee/ ]XBee
does a very good job of acting like a serial wire...maybe connecting the
Redpark cable wirelessly to the Arduino.

(Warning - tangential reference ahead)
For those interested in the Desktop to Arduino connection:
I've managed to replicate some of Corni Cornaz' great work, done with the
desktop version of LiveCode and Arduino, using the XBee.

Corni did a [ http://www.ustream.tv/recorded/13729531 ]LiveCode TV
presentation and also put his stack on line here:
www.claudi.on-rev.com/livecode/experiments/

Corni has done a great job of documenting the precarious serial
communications protocol pitfalls in LiveCode on the desktop side. His
prototype stack demonstrates two way serial communications with the
Arduino, and was simple as pie to convert to an XBee based wireless
connection (yes, really).

(Lastly, for a future discussion and an exercise left for the reader,
insert the words "Raspberry Pi" where ever you see "Arduino".
Sadly, Radio Shack has not yet embraced the Pi.)

As always. sorry for the ramble - and thanks for any thoughts you may
have....
