Hopefully someday, when I get around to it (ha!), I'll be able to  
document my experience with lighty and Horde.  Having set up server  
farms that need to handle thousands of connections per second, the  
ultimate conclusion is that you are absolutely crazy to still be  
running Apache + PHP.  A FastCGI based farm is easily 300%+ faster on  
identical hardware, not to mention much easier to scale.
