There is a common misconception here ... the GPL does not make any 
distinction between commercial / non-commercial usage.  The only thing 
that matters when you're dealing with the GPL is distribution: if you 
distribute your derived work (outside your company), you must do so 
using a GPL-compatible license.  If you don't distribute, you don't have 
to do anything.

Cheers,
Tim
