Portable hard drive for poker apps?

[ds914]

Is anyone currently using a portable hard drive to move around their poker apps between different computers?

Ideally, I'd like to have three Party skins, Poker Tracker and PlayerView in a portable format so that I can use it at home, at work (if/when time allows) and perhaps when I'm on the road.

Can these programs run off a portable hard drive, or are they meant mainly for data files only? Is anyone currently doing this? Do you have one that you'd recommend?

I'd love to know that I can take my PokerTracker database with me.

Thanks...
