Instead of lifetime free evaluation, have a "free account". and the options for them to updgrade there account status's.
This is something I am interested in also. I want to offer a "free" account that has few features, which would also give users an incentive to upgrade for more features.
If they have upgraded, when that paid account "expires" it simply drops the user down to the free account status - once again limiting the features.
This means we can still keep the user onboard.
