Correcting myself:
I think it is a design error to carve _any_ toolkit or GUI in stone.
There things should be configurable and need an API that describes
the necessary functionality, which is then mapped onto certain
configurations.

Kepping this choice open and not forcing the user/developer to
finally decide makes the project more valuable and flexible.
It also avoids that specifics of GTK, QT or what ever show up
through the whole layout, which would influencing the overall design.

So I'm actually trying to draw a slightly bigger picture with pluggable
components.

To get more specific again:
What is "Precise"? I tried to find out with not much effort, and I have
to admit that I'm not a Ubuntu developer, but seeking for the simplest
efficient solutions.

My intention is to make things run smoothly under
- OS X
- Windows
- Linux (Debian)

which is the order of importance for me.

Then, I would like to include a different approach as an option, which
is of value for testing: Using a VNC interface instead of direct frame
grabbing. This gives more flexibility and a better abstraction and allows
to decouple the system under test from the OS of the test implementation.

Not saying that I want to actually do everything, but to keep the choices
open.

Well, enough brain dump for now ;-)

cheers - chris
