Don Park explains why you always have to read the license for software products:
My situation is a common one in that I will have a single server driving several websites and web services, some of which will be commercial. More servers might be added later, but still located at a single data center (ServerMatrix). BDBXML license allows free use under this situation. But the software that runs on my server(s) is being written at home which is in a different state. Since my development machine is in California and my production server(s) are in Texas, I am in fact redistributing whenever I upload my software to the server(s), violating free use under BDBXML license.
Liz Pennell, Account Executive at Sleepycat Software, confirmed this but, recognizing that this might discourage developers from developing software based-on their new product, they graciously granted me free license.
Kind of makes me wonder how many people are violating licenses without knowing it. Funky....
