Can you download unity editor onto a USB device?

My Computer doesn't have enough space for the unity editor and I was wondering if it is possible to move the program to a empty USB device with 2GB. My computer does have enough, but afterwards my computer will have 12MB left.

It should work fine, I would personally run Unity from the computer though as it would be faster. I have all my games saved onto Hard Drive and even that is slightly slow when testing the game.

12MB left?? Really? Thats kinda 'sucky' for a developer/designer ;)

Search for your answer... I find if google'ing, add in a unity3d at the end of what you need, and it comes up with plenty of things...
