Slight clarification. You have to abide by the terms of the GPL no
matter what, but the terms of the GPL (might) not cover in-house

The idea that "in-house" distribution isn't distribution and doesn't
invoke copyright claims is purely the opinion of the FSF, isn't
explicitly stated in the GPL, (maybe in GPL 3? I haven't been keeping
up) and isn't supported by case law. This means that people who
distribute under the GPL but do not agree with the FSFs definition of
"distribute" may have a problem with in-house development that doesn't
obey the GPL.

As a final note, *using* Eric or any other application written in
Qt/PyQt doesn't have any effect on you - this only matters if you are
writing your own applications using Qt.

As a doubly final note, this isn't legal advice, I'm not a lawyer, ask
lawyers, not the internet, for legal advice, etc, etc.
