In-house you can do what you like with the code. If you want to
sell it, even if it's in some kind of "black-box", you have to make
the source available on request. Or you just broke the GPL.

There's no fee needed, you are free to charge whatever ridiculous
price your customer pay, the GPL is not about money, but about
open code.

AFAIR there have recently been some cases, where a "black-box" was
sold as firewall, which in reality contained Linux/iptables/etc,
those manufacturer somehow forgot about the GPL and didn't made the
source available upon request. They settled with the FSF Europe,
payed rather large contributions and promised to stop breaking
the GPL, there was at least one "global player" manufacturer among
them, so better don't even think about breaking the GPL.;)

You should find complete/correct info, since I'm no lawyer and
the above was written from memory, right over here:
