I used to use that method -- only querying if you were hovering over  
the contact and thus a tooltip was needed -- but you can have a delay  
in the response, and I ended up with a bug report of 'the first time I  
mouse over contacts, their client information doesn't appeal!'

In addition, one of the more common usage scenarios seems to be that  
various clients use the client information to display a default avatar  
if the user doesn't have one set (i.e., showing the Psi logo for Psi  
users, an iChat chat-bubble for iChat users, a Google chat-bubble for  
Google Talk users, and so on), in which case, the 'I need client  
information' usage case is 'the person came online.'
