I use Ubuntu and what I have in mind is this:
1) Create a folder in Ubuntu One to save my minecraft game
2) Make the new location the default location in minecraft.
This way, I would be able to play my world on a computer A, exit and save.
Ubuntu One will synchronize the saved game with every computer set on my Ubuntu One account.
On computer B, I turn on minecraft, and access my previously saved game and all the new changes I made on computer A, from computer B!
With this configuration I should be able to play around the world seemlessly.
I've posted this here because my problem is not an Ubuntu problem, it's a minecraft one.
How can I configure minecraft to access this folder in Ubuntu One. Which piece of code should I change?

I can't test it right now (At work) but I believe Minecraft stores its configuration data (and world data) in "$HOME/.minecraft".
If you replace that directory with a symlink to a folder in the Ubuntu One folder it should use that new folder to store it's data, if you do the same at a different computer the game shouldn't know the difference.
