there is nothing special about network communication outside of your lan. if this app lets you type in an ip address, and your computer has a ip thats visible from the outside world, it should work. promising that this app lets you take your work with you is a little misleading however, because the hardware you have in your home might not allow you to make your network visible to the outside world.
 
What would happen if you attempted to watch a Hulu video (running in a web browser on your Mac) on an iPad using this? Is that even possible?
