This looks pretty interesting (and I particularly like the ability to have a package pointed at the bleeding edge), but I'm not sure how I feel about /usr/local being owned by an arbitrary user. What happens if there's more than one user on the machine?

You can have homebrew reside in any place you want on your hard drive. The Readme actually suggests to first install it into a directory "brew" in your home dir. You just need to adapt the $PATH in your bashrc accordingly.

From my own experience: beware with moving that directory after installing some formulae somewhere else. It caused quite some trouble for me and i wound up recompiling everything in the new directory.
