It is a gamble. You are paying interest up front as point for the lower interest later, but if interest drop, you lost the advantage you paid for.
At the current interest rate, if you believe that it will not go any lower, and if you believe you will stay in this house for a very long time to justify the lower payment, and you have the income stability to pay for it for the long term (no layoff, no bankruptcy, no relocating for a new job), then it is worth it.
IMO it is just too much restriction consider that you can get very good rate fixed with no points, and not having to worry about whether you wasted your money buying points.
