For a few years I have used an Atom UMPC as my "mobile development
terminal", allowing me to build and run code at much lower performance
than I would expect from a "real" system but good enough for working on
new bits of code and finding performance bottlenecks :)

I am migrating over to a Nexus 7 with a Debian chroot environment and
tightvnc for display. This is working great for most things.  The last
bit is to be able to run jackd so I can actually test audio parts of the
programs I work on the most.

I don't care about latency, or even xruns.  This isn't for production
use.  I just want to be able to exercise the jack client library, make
connections, and hopefully get SOME audio output.  The current problem I
am having is that sys V shared mem API is not supported.

Has anybody done anything like what I'm working toward?  Any workarounds
for missing shm API?
