Using unix groups for different read/write access in a single repository

Hi

I would like to use single repository for several different projects.
I need to give a read/write permissions based on a unix group for each one
of the project and the permissions must also deny reading from other
projects.

What is the way (if exist) to do such thing?
Should I use a different repository for every group?

Thanks!
