I use jaws on a flash drive on a regular basis. It will only run in 40 minute demo mode. This can be a real pain when you are working on a computer and the time runs out. You can't just turn jaws off and then back on again. You have to do a restart and that really sucks. Other than that, it works great and is good to have.
