Sean,
 
I think the same way as you, but I told that as the only way to have no concerns about this possibility.
 
And below, Helen Borrie speaks about this concern. Since the concern exists, the possibility exists. And, as one of Murphy´s law say, if it´s very difficult to something happens, than, it will happen.....
 
Thinking that over and over the customer is correct, nothing better than resolving this kind of situation using clearly a licensed product. If he pays, than he will have clearly no more concerns.... doesn´t matter what we think and use about GPL.

Whether you agree or disagree, the IPL and IDPL licences refer to the right to copy the source code, not the right to deploy binaries.  It is not because of the licences that people get Firebird free of payment.

Ask your customer if he has licensing concerns about using the Firefox browser.

If not, have him open the browser, go to Help | About and click on the "Licensing Information" link. 

Then have him compare the wording of the Mozilla Public License (MPL) against the InterBase Public License (IPL).

He will find that they are 99% the same.  The only substantial difference being that the name "Mozilla Project " has been replaced with "Interbase Software".

So, he should have no more concern about using Firebird than he does with Firefox!


Sean
