So, I am just a lurker here.  I mostly follow hackers to find out if  
any new features are coming out that will make it worth upgrading, and  
to keep up on any backwards compatibly changes that I should be aware  
of.  I am on 8.1 and it performs well and no features added since then  
have seemed worth downing the whole system to do the upgrade for.   
However, a simple to administer, query-able slave that does DDL  
transparently and is up to date within a controllable time frame is  
something that would undoubtably make it worth the upgrade.  Whatever  
version this feature makes it into will probably be the one I will  
upgrade to.

Of course this is just one developer giving you anecdotal evidence and  
there are obviously many concerns other than just how in demand it is,  
but I just wanted to register my vote that this is a very sought after  
feature and it is hard for me to imagine a situation (especially for a  
24x7 web application) where having an easy to admin hot standby server  
wouldn't help your local DBA sleep better at night.
