Gotcha - that makes sense.  Where are you looking to have the link show 
up?  If you want it to show up in the preference screens or the top 
menu, you could write something fairly simple that does a database 
lookup and based on the results, switch the link to Vacation or Ingo.  
It wouldn't be a Horde Hook, per se, but you could still implement the 
logic therein and switch one way or the other based on your SQL lookup.
