OSX + Windows suite

Hi everybody,
It's been nearly one year since I use portable apps.
I use them on windows and Linux(Wine) everyday.
But I miss quite a lot using them on OSX, so I've been very happy when I discovered

, but, a little bit disappointed.
Disappointed because I need to have the .exe(win) and the .app(osx) sharing the same profile folder.
And I really don't know how to do this.
Can anyone help?

Thanks everybody,

Nicolas.
