Hi Dave, No, this module shell should be available for all people without costs accorded GNU licences.

Best wishes

Sven,
I think this a misunderstanding of the GPL.

Citing from GPL 2.0 §11: "Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version."

This means that of course everybody may use a product licensed under the GPL to make money. Otherwise it wouldn't be possible to sell e.g. various LINUXE's. Sellers only have to abide to the rules of the GPL. GPL products are used in a variety of commercial products, e.g. various routers, the majority of servers in the Internet world - and what have you.

In this specific case, Dave can simply use your work to offer the products based on your work, provided he does it mentioning your copyright under the GPL. So while he could simply do so, I guess he would feel better if you, after reviewing the GPL, would give your explicit consent.

Remember, GPL is not like "free beer"(*) but like "free speech"

HTH, Günter - but INAL

2.PS: I once wrote an email to Angel with respect to his preface to the documentation of his fine work, mentioning that his wording is in contradiction to the GPL. Well I didn't receive an answer. But this again shows that it is absolutely necessary to carefully read the GPL, before publishing one's work under this license.
