Right-o, I'll check it in during the week. Just got a
few more things to take care of first though.

No worries here ... you can just think of QNX as another
Unix. You can buy the core OS ... which comes with the
standard libraries and API's. Then you can buy the windowing
system ... which comes with a standard/documented API and
programming tools. The main difference here is that because
QNX is a micro-kernel you can in fact just buy the components
that you need. There is lots of other GPL software running
on it so I don't think that this is any kind of an issue.
There are no secrets hidden in the AbiWord code, all just
standard API calls.

Yup ... If you buy the photon window manager components then
you would be able to run a binary version of AbiWord. If you
buy a development kit (compiler etc) then you could compile
your own version of AbiWord.

Yeah I explained that to our company head and the R&D
manager. I'm using Neutrino (QNX Softare Systems next
generation OS ... it is the successor to QNX 4.xx) here
to do my development. We have a couple of different
installation options and I'm in the process of getting
permission to ship you guys a free copy of the software.
You should be able to get it up and running on any x86
machine that you have in house. I'd like to get you
guys into the Beta program for Neutrino ... but there
would be NDA's to sign and the like so let me know if
you would be interested.
For a better idea of what is supported under NTO you
can look at:
Basically though we support most major devices. The
graphics cards right now are the big issue, more
so in Neutrino than in QNX4, but that will change
soon as well.
