Setting the SUID/SGID bit for a program to the 'root' user should actually be discouraged. If the program is badly written and can be manipulated via (malicious) input, it could allow a normal user to gain root privileges or access to files which that user should not be able to access.
When setting the sticky bit to a normal userid, it could allow other users access to all the other user's files, which may not really be what you want.
So please think about the security implications before randomly using this feature.

If you are facing a permissions dilemma for multiple users/groups, please consider looking into MAC (Mandatory Access Control).
