Yes, and yes. You need to use Identities if you allow your users to 
have identities. And yes, with large lists this might be a perfomance 
hit. OTOH, if you  use hooks anyway to propagate the users' identities 
with reasonable default values, you could use the same code in the 
username/backend hooks to show the full name.
