Can you name some other things that use the approach you mention?

Sorry mate, but if you having problems with MySQL then it's not the
fault of the programmers that wrote MySQL - that's for sure.
You've got to ask yourself why you are using MySQL - legacy hangover?
You've got to choose the right tools for the job - maybe the tools
that were originally chosen either:
- Weren't the right ones to choose - ever.
- Were the right ones at the time but the plans never accounted for
I'm with the application layering folks on this one. If something is already
there, does a good job and saves you time - then go for it.
That said, I am one of those people who developed some CORBA-load balancing
stuff using the CosTrading a couple of years ago. One of the reasons I chose
that approach was that IIOP is one of those protocols that firewalls and NAT
doesn't like. It was interesting for sure, but I'm glad to say that there
plenty of app servers on the market now that happily take care of load
balancing (and probably make a better job of it than I did!)
