What follows is a Trolltech response to my direct request regarding this
very issue.
.....
Qt/Embedded is licensed both under a commercial license and under GPL
(the socalled Free Edition). The versions are identical code-wise. The
only difference is in the licensing. We provide Open Source developers
with the same high-quality tools as the commercial developers get.
This means that you can develop Qt/Embedded software free of charge if
the software you develop is also released under the GPL license (thus
open source). Furthermore, as long as the device you install this
software on is only delivered with GPL'ed software you can also use
Qt/Embedded on the device without purchasing runtime licenses.
In case you develop closed source software for your organization or
another customer, we can offer you commercial development licenses and
runtime licenses for the end devices. If you develop GPL'ed software for
a device which also is delivered with closed source software, the device
needs runtime licenses for Qt/Embedded.
Commercial customers will benefit from professional support and services
and will not be restricted by the GPL licensing conditions.

Note that this says that as long as ALL of the software on the device is
GPLed, then you're OK...
Our MyLinux Pocket Linux Workstation project uses only 100% GPLd
software and other GPL-like licenses for things such as
NanoZilla...etc...so we're clear in terms of this response, however, my
reading of the GPL isn't exactly this way. I probably need to re-read
the GPL to see if I can gleem anything new regarding this specific
point, but at least you now have this response from Trolltech...besides,
we're currently using mostly Microwin/Nanox for now, anyway :)
Take Care.
Rob!
