yep, we have tested this on Raspberry Pi and Freescale i.MX6 systems running 
Linux. It has also been successfully used on (OMAP-based IIRC) QNX/BB10 
systems, but there you might still need some manual fiddling with LD_PRELOAD 
to get it working. We also have tested it on a system with a custom stripped-
down Qt5 that doesn't contain QtWidgets. In the unlikely case the target 
doesn't have QtGui either, some more work is required to completely split this 
out into plug-ins. It also compiles fine for Android, but we haven't looked 
into how to do the injection there yet.

For cross-compilation with CMake you find a few example toolchain files 
checked in (cmake/ subdir).

The communication protocol is based on QDataStream and thus works between Qt 
versions, between operating systems and between architectures. We have tested 
various combinations, but I think we had a strong bias towards little endian 
systems.

regards,
Volker
