Very cool! We were just discussing the need for something like this as we have a hybrid on-site/virtual team so our Planning Poker meetings become a bit difficult.

Couple of suggestions: 1) Allow flexible cards...the numbers we tend to use are slightly different 2) Allow mass import of stories once the game has started. Ideally I'd have one persistent URL that I can use in our recurring invite, instead of having to create a new game every time we enter planning. But since I can only do a bulk import when creating a new game I'd have to get a new URL each time.
