Yes, it does.

Yes, it will show s1.lite.msu.edu.  The domain colors & logos set for your 
school will be shown to the student as they are logged in under that domain. 
Aside from the address bar there will be no visual indication the student is 
logged in to an MSU machine.

No.  No offloading of users happens if the machine the student is attempting 
to log in to is a library server.  It only happens if the student is 
attempting to log in to an access server.

It is based on the values for lonLoadLim & lonUserLoadLim in loncapa.conf.   
If your access server exceeds either of those limits AND the offload target 
server is not itself overloaded, the student will be sent to the offload 
target server.

It's not a problem at all!  It means when I forget all this information I 
can just go to the mailing list archive and look it up :)
