As a former business traveler I must say that this is a great idea!  I really could have used this on many occasions.  Not sure how well it would work, but you can’t beat the portability when every once counts.

The Jelly Click takes mouse portability to the extreme. All the electronic circuity lives on a small flexible board. The body itself is just soft plastic. Whenever you need a mouse, blow up the Jelly Click, attach the USB cable and you’re good to go.  As a bonus, it’s a total floaty for you swimming challenged people.
