SEQUEL Authority

Hello, we've just started using SEQUEL and have a decision regarding security 
that I'd like some input on, if possible.  
 
We have a library that's always been public *exclude (access via AA - adopt 
authority, no that AA), and we want to allow users to access it as *use only so 
they can use SEQUEL to query it.  
 
How have you allowed giving users access read only to a library without 
updating the authority/autl's?  We have dozens of grpprf's and hundreds of 
usrprf's and not all the mbr's of the grpprf's will get access to SEQUEL.    
 
I was thinking of creating a signle usrprf (called SEQUEL) with *use and then 
using the SEQUEL profile swapping program.  Is that what you SEQUEL admins have 
done for this access, or is there another (hopefully simple) way?  
 
Also, giving SEQUEL access to a few hundred users, any impact performance-wise. 
 Are there any tips to avoiding performance issues when running SEQUEL for many 
users? 
 
Thanks, Frank
