We handle this by having a web-based tool wrapped around the groups 
functionality.
The tool allows managers of a code line to control who can check in to a 
code line.

The code lines are defined in the protection table.  I've always wanted 
to extend it to use a trigger so more helpful error messages can be 
returned.  The default error message when someone can't submit a file to 
a locked code line ("no permission to lock file") can be rather confusing.
