On the RaspberryPi website the question about the absence of audio-input was answered recently:

There are no inbuilt Audio ADC’s so there would be a cost adder – everyone was sat on my head to get costs down. They can be easily added via the GPIO.

So, still a possibility in an embedded openstomp-ish device.

An arm-based device I would like to have pd on is the Pandora, based
on the OMAP3530.
Which has audio-in/out and gpio on a single plug.

Combining that with a stompbox that holds, for instance, an msp430
(launchpad, by ti) with an lcd-screen and some nobs would make for a
very nice interface :)

Still looking in to compiling for their OS.
The pandora is then again a very small niche, hence I was reflecting
on the current interest towards the RasPi.
However I didn't realize this device doesn't have line-in, so that
indeed is a little discouraging.
