Nope. We wouldn't be able to function as a business if our customers did that. We wouldn't be able to support the server infrastructure alone, setting aside the tremendous amount of resources we put towards new developments that we release as part of the LimeLM subscriptions.
There are cheap and crummy licensing solutions out there. If the lowest price is what you're looking for, you'll have to look elsewhere.
If a reasonable price with great technology is what you're looking for, then I'd say give LimeLM a try and see if it fits your needs.
