Al, just following up:
>>The Devart driver includes encryption which is cool, but it's US$150 per license (machine). I didn't see any offer of royalty-free distribution but you could contact them.
From Devart FAQ:
Do the end-users of my own product that uses the Devart assemblies need a license?
No, end-users of your application do not require any license.
Do we need a separate license to deploy our application to customer's site?
If you have the Devart license, you do not need to pay any additional fee for deploying or distributing your software to end users.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
