Do you want to protect from customers buying less licenses than they really need? That's exactly it. I know there are some people who are dead set against paying for software, and they'll break whatever we do. Those people weren't our customers anyway. Another question is: how do you license your software? Do you give a serial file? Serial number? Is it available for download? Serial number but not currently enforced. Fairly high-end (~$800/license), primarily enterprise users. Can be downloaded online, but there is no 30 day trial (would very much like to change this). Phone activation will make you lose sales. Don't annoy your customers. Just make it clear what they can do and what they can't do. Definitely, we just need the vendor to provide phone activation as a fallback for customers who don't want to / can't activate online. Thanks for giving this a look.
