It took a while for the page to load, look into YSlow or that new Google PageSpeed to optimize it. Also took a couple minutes to grok what it does. Once I did, I immediately wanted to get it but was hesitant about how much it cost. I didn't see any mention of price anywhere. If it's free, be sure to mention that somewhere (preferably in big bold letters).

All in all, it looks like you guys have done quite a good job. Good work and I'll be one of your users soon enough (once I get home and can open port forwarding).
