I'm not sure exactly what feature is required, here. f5s of my  
acquaintance are already very capable of making OSPF LSAs based on  
virtual servers' pools being non-empty. Do it on more than one f5 in  
the same area, and you're anycasting service availability with the  
current feature set.

The general reason why people prefer to find alternative solutions  
rather than use dedicated load-balancers are that the dedicated load- 
balancers are hellishly more expensive than the $5 gigabit switch you  
probably already have in your garage.
