I believe you can market and sell your SERVICES to clients, but any code (module) written to expand the functionality of software written and distributed under the GPL MUST NOT be "exclusive/copywritten".. If one of your customer's decided to contribute back or share one of your "copywritten" modules, technically the GPL says they should be able to..

we needed to use distribution terms that would prevent GNU software from being turned into proprietary software
Copyright implies proprietary.. BTW, the placement of your code on a client's site is a form of distribution..

Dr.Byte, if you was ever going to jump in a conversation.........now's the time, as I could REALLY use some advice about this, and I know you're the 'All knowing' around here.

I just need to know if what I'm pointing out above is within legal boundaries, or if there's ANY way or absolutely NO way to do this without getting myself in trouble. I sure don't need that!
