Yes, it works also without becoming root, because no installation is needed. You do have to call
source /nfs/mount/for/root/bin/thisroot.sh (for e.g. bash) or
source /nfs/mount/for/root/bin/thisroot.csh (for e.g. tcsh)
before starting ROOT to setup environment variables, so ROOT can find its files. Alternatively you can set them in your ~/.bashrc (or equivalent).

Cheers, Axel.
