I'm currently working with Nokia and Linaro to lay the groundwork for
this, by way of extending libjpeg-turbo to support NEON SIMD
instructions on ARM platforms.  I haven't actually looked at porting the
client yet, however.  The best approach would be some form of VNC
viewer, since X11 doesn't exist on iOS and it's not straightforward to
get working on Android.  There are at least two VNC viewers available on
iOS (including one from RealVNC), but they aren't open source, and
neither of them is going to perform well enough to use VirtualGL at
interactive frame rates.

I have funding to work on this for Android (as well as test hardware),
so that will be the platform I focus on.  One intriguing project is
vnsea (http://code.google.com/p/vnsea/), which claims to be an open
source iOS VNC Viewer.  It would seem that integrating the TurboVNC
decoder into that project would be a fruitful way to get a high-speed
VirtualGL client on iOS devices, but I don't have funding for anything
iOS-specific.  Android-VNC-Viewer is most likely what I'll look at
integrating with (http://code.google.com/p/android-vnc-viewer/), since
it already supports Tight decoding and would be straightforward to
extend with the Turbo decoder.

Further, Linaro is actively looking at integrating libjpeg-turbo into
the core Android O/S, so it may be possible in the future for me to
leverage that without building my own version of libjpeg-turbo on Android.
