LOL. Messaging systems are reliable? That's a good one.

I've been neck deep in messaging systems for the last two months, and 
"reliable" is the last word I'd use to describe them. The first word I'd 
use? It's hard to pick, but "annoying", "hideous", "buggy" and 
"error-prone" all come to mind. We're getting ready to rip out the 
messaging system completely because it just can't handle, well, anything.

Possibly if you've got the budget for MQSeries and multiple expensive 
professionals dedicated to babysitting it full-time, you can make 
messaging reliable. I've certainly heard bedtime stories about companies 
that run like that; but on anything approximating a startup or small 
business budget, messaging is a sure-fire way to kill a system.
