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!
