Cloud option for inventory

It would be very nice if there were a "cloud" option for my desktop inventory list. I take my smartphone with me to the local Home brew supply store. I could view my inventory on it, see that I am low on this/that, without making a freaking "grocery list.
How about some updates?!

I wonder if the mobile app has been integrated with the desktop version at all (usb)? Still a hold out hoping for something useful.
