Mass Effect DRM question

[GodlessAstronomer]

I'm at home at the moment on term break and I bought Mass Effect to pass the time. I have installed it on my brother's computer with no problems. My question is, when I go back down to uni will I have problems when installing it on my own PC? I have heard that the game "phones home" from time to time so I'm guessing I will need to uninstall it from my brother's PC before installing it at home, is this correct? Will I run into any problems here?

It only "phones home" the one time you install it and I think you can install it on up to three computers at the same time.

I'm not sure if there is a activation revoke tool like there is for Bioshock yet.

That's cool, thanks for the info.
