My use cases for stem aliases are similar:
1) Supporting multiple hierarchies so that stems/groups can be found 
straightforwardly by individuals with different roles and, therefore, 
different expectations - this is similar to Bert's use case where 
department members have different needs to a sys admin.

2) Sometimes a strict hierarchy just doesn't work - we have course modules 
which may be taken by students on different courses from different 
departments. From the Staff or Student point of view groups associated with 
the module belong under both department/course trees. This is more a 
navigation issue than wanting stem aliases to be interchangeable in config 
files.

Given that course modules etc will often be represented by more than one 
group it is often more appropriate to create a stem alias than lots of 
group aliases. I understand there are more implications for stem aliases 
but it has been on my wish list from the very first call Bristol had with 
Tom and blair when we got involved with Grouper - more consistency Tom :)
