No body tried so I did
just installed on my usb disk & I am able to install all my softwares (YES ALL software) & can connect to any PC mine or in the internet cafe & use my usb as my portable desktop.
That great solution.
So now just install XP on ur C drive & no need to install any other program on desktop C,
connect usb & install mojopac on usb drive
you need to make some config changes to usb hardware properties.
then start mojopac &what it does is it adopts host system & now u install all ur softwares on this C drive (actually mojopac drive)
So now whenever u loose XP , any virus, or any other trouble u just need to reinstall or repair XP on ur desktop system.
No need to reinstall all ur programs.
Isn't that great?
Note: this works even on usb sticks but will be too slow i guess, I have installed on a usb 2.0 device which is 7200 RPM seagate portable disk & it works like a normal PC.
