[PD] using pd live (sans computer/laptop/raspberry pi)

Without a computer, no. Without a desktop or laptop computer, yes.

An embedded computer (rpi or UDOO, for instance) can totally do this and
that's what some of us have used them for. Simplest case is to setup the
system, install pd with your patch, and write a script that is launched
when the machine boots that connects to the sound card and starts pd. This
way it starts immediately when you turn on the power, no interaction
required. All of this can be built into a box of some sort, giving you an
in/out effects setup. It's what I've done with several systems, although
they are not as small as a real pedal.

Any regular USB sound card will work. I recommend the Roland Edirol UA-25
 o/ UA-25EX as it's a simple USB 1 sound device that will work with
anything that speaks USB audio without a driver. You get instrument
jack/XLR preamps in and stereo out.

You could also get this setup with my Pd iOs app
Chris McCormick's
PdDroidParty <http://droidparty.net/> and a sound interface to your mobile
device. For instance, I have an Alesis iODock for my iPad which gives me
the equivalent of a UA-25. I've also had success using a UA-25 with a
powered USB hub connected to the iPad via the camera connection kit usb
adapter. Let me know if you want to beta test PdParty as it's currently not
released on the App Store.
