Root automatically has full access and doesn't need special 
consideration.  One of the other users (svradmin) can be the owner and 
have rwx permission.  To allow access by additional users you can add 
group rwx permission and put the users in the of the files.  Having a 
single other user is a slightly special case where you could give 
edward's group to the file instead of the other way around.  In any case 
you need to be careful when creating new files to set the correct group.
